MedWave Group Reviews and Scam Concerns: Our Investigation of the Optimum-100S

Anyone searching for MedWave Group reviews, MedWave scam, Optimum-100S reviews, or Optimum-100S scam may want to review the experience documented in this report before purchasing equipment from the company.

We received screenshots and a screen recording from a prospective purchaser who contacted MedWave Group while investigating the Optimum-100S, formerly known as the Contour-100S, for use in a wellness-related business.

The inquiry focused on MedWave’s claims regarding red-light therapy, body contouring and fat reduction.

After reviewing the correspondence and MedWave’s publicly available product information, we believe the interaction raises serious scam concerns, particularly because the company declined to answer several basic technical and clinical questions before terminating the inquiry.

The MedWave Optimum-100S / Contour-100S

The product investigated in this report is the MedWave Optimum-100S, previously marketed as the Contour-100S.

MedWave advertises specifications including:

• 635 nm red light
• 585 LEDs
• approximately 95 mW/cm² power density
• 30° optics
• claimed 3–4 cm tissue penetration
• approximately 20-minute treatments
• body contouring
• fat reduction
• cellulite-related applications

MedWave has also described the system as capable of helping mobilize stored lipids from fat cells and has promoted combining treatment with physical activity or its HyperVibe vibration platform.

Because these are measurable technical and biological claims, the prospective purchaser wanted to verify them before spending a substantial amount of money.

The Technical Questions Sent to MedWave

The prospective purchaser asked MedWave for information including:

• the distance at which the advertised 95 mW/cm² irradiance was measured
• the recommended treatment distance
• the actual irradiance reaching the skin
• the output of the Low, Medium and High settings
• the delivered dose in J/cm²
• whether the LEDs operate continuously or are pulsed
• pulse frequency and duty cycle, if applicable
• total measured optical output
• evidence supporting the claimed 3–4 cm penetration depth
• clarification of whether the advertised 5 W per LED refers to electrical power or actual optical output

They also requested clinical and regulatory information, including:

• studies performed specifically using the Optimum-100S
• studies performed using the former Contour-100S
• objective measurements of fat reduction using ultrasound, MRI, CT, DEXA or similar techniques
• regulatory authorization or registration specifically relating to body contouring or fat reduction

These are not requests for manufacturing diagrams, software, circuit designs or trade secrets.

They are questions concerning the measurable performance and evidence behind a product being marketed commercially.

MedWave Responds: “We Will Not Be Sharing Our IP With You”

MedWave’s initial response was:

“We will not be sharing our IP with you.”

The prospective purchaser then clarified that they were not requesting confidential intellectual property.

They explained that they were only asking for publicly available or customer-facing information such as treatment dose, irradiance, clinical studies and regulatory information.

MedWave subsequently responded:

“If you have a Wellness business or if you want to purchase a device for home use, we are happy to arrange a call for you with one of our experts. They will discuss with you what the best device is for your application.”

The purchaser explained that the inquiry related to a wellness business and stated:

“But I need details before I purchase”

MedWave then requested the business website.

Shortly afterward, MedWave ended the discussion with:

“MedWave is not a good fit for you. I will be removing your inquiry. Thank you”

No substantive answers to the requested technical and clinical questions were provided in the correspondence submitted to us.

Why This Raises Serious Concerns

The issue is not simply that MedWave declined to disclose proprietary intellectual property.

A company is entitled to protect genuine trade secrets.

The concern is that MedWave appears to have treated questions about basic measurable specifications, clinical evidence and regulatory status as though they were requests for confidential IP.

When the prospective purchaser clarified the distinction, the company ultimately terminated the inquiry.

For a high-value wellness device promoted with measurable claims such as:

635 nm wavelength

95 mW/cm² irradiance

3–4 cm penetration

fat reduction

and:

inch reduction

we believe prospective purchasers should be able to ask how those claims were measured and what evidence supports them.

What We Found Regarding the Scientific Evidence

There is scientific research investigating 635 nm photobiomodulation and low-level light therapy for body contouring.

That means the general concept itself should not automatically be dismissed.

However, the important question is whether research involving other devices proves that the MedWave Optimum-100S specifically produces the same results.

During our review, we did not identify a published randomized, sham-controlled clinical trial clearly naming the MedWave Optimum-100S or Contour-100S as the device being tested for fat reduction.

That matters because photobiomodulation outcomes can depend on factors including:

• wavelength
• irradiance
• treatment distance
• optical geometry
• exposure time
• J/cm²
• pulsing
• treatment frequency
• number of sessions

A study involving another 635 nm device does not automatically validate every commercial machine using 635 nm LEDs.

Why Independent Testing Matters

Many of MedWave’s advertised specifications can be independently tested.

A calibrated spectrometer or spectroradiometer can verify wavelength.

A calibrated radiometer or optical power meter can measure irradiance in mW/cm².

Treatment time combined with irradiance can determine the delivered dose in J/cm².

A photodiode and oscilloscope can determine whether output is continuous or pulsed and measure pulse frequency and duty cycle.

An integrating sphere can be used for more detailed optical-output characterization.

Actual changes in subcutaneous fat could potentially be measured using techniques such as:

• ultrasound
• MRI
• CT
• DEXA

These are objective questions.

They do not require disclosure of MedWave’s manufacturing secrets.

Our View: MedWave Group Scam Concerns

Based on the information submitted to us, we believe MedWave Group raises serious scam concerns and should be treated as a high-risk purchase until its claims can be independently verified.

Our concern is based primarily on the following sequence of events:

A prospective purchaser asked for measurable technical information and supporting clinical documentation.

MedWave responded that it would not disclose its intellectual property.

The purchaser clarified that proprietary information was not being requested.

MedWave offered access to an expert, established that the inquiry concerned a wellness business, requested the purchaser’s website, and then terminated the inquiry without answering the core technical and clinical questions.

For us, that level of resistance to straightforward product verification is concerning.

We would personally not recommend purchasing the MedWave Optimum-100S based solely on the marketing claims currently available without first obtaining independent verification of:

• actual wavelength
• actual irradiance at treatment distance
• delivered J/cm²
• penetration claims
• device-specific clinical studies
• objective fat-reduction evidence
• relevant regulatory status

If MedWave later provides independent laboratory testing, device-specific clinical trials or verifiable regulatory documentation, that information should be considered.

Until then, prospective purchasers researching MedWave Group reviews, MedWave scam concerns, Optimum-100S reviews, or whether the Optimum-100S is a scam should exercise significant caution and conduct their own independent due diligence.

Client Marketing Services (CMS Voice) Reviews: Warning About Unsolicited Telemarketing Calls

This Client Marketing Services (CMS Voice) review is being published to warn consumers and business owners about an unsolicited sales call I received from someone claiming to represent CMS Voice.

The caller asked whether I wanted my business to be found through Siri, Google voice search and other voice-assistant platforms. When I requested the company’s name, the caller identified it as CMS Voice and provided the website CMSVoice.com.

According to the CMS Voice website, the full company name is Client Marketing Services. The website advertises voice-search optimization and business-listing services intended to help businesses appear when customers search through Siri, Alexa and Google Assistant.

My Experience With a CMS Voice Telemarketing Call

I did not request this telephone call, submit an inquiry or ask CMS Voice to contact me.

During the call, I informed the representative that my telephone number is registered on Canada’s National Do Not Call List and that I did not consent to receiving unsolicited telemarketing calls.

Receiving calls of this nature is especially frustrating because similar sales callers frequently appear to use different telephone numbers. A changing caller ID can make it difficult for consumers to recognize, block and document repeated calls.

I cannot independently confirm whether the telephone number displayed during my call was owned by Client Marketing Services, spoofed or operated by a third-party call centre. However, the caller specifically identified the business as CMS Voice and directed me to CMSVoice.com.

Is CMS Voice a Scam?

Based on a single telephone call, I cannot conclusively state that Client Marketing Services or CMS Voice is legally proven to be a scam. However, I consider the unsolicited nature of the call a serious warning sign, and I would strongly recommend that consumers exercise caution before providing:

• Credit-card or banking information
• Business login credentials
• Google Business Profile access
• Personal identification
• Authorization for recurring payments
• Verbal agreement to purchase a service

The CMS Voice website itself states that the company is an independent service and is not affiliated with, authorized by or endorsed by Google, Apple or Amazon.

Consumers should therefore understand that a call about appearing on Siri, Alexa or Google does not necessarily mean the caller represents any of those platforms.

Client Marketing Services and CMS Voice Reviews

Anyone researching Client Marketing Services reviews, CMS Voice reviews, CMSVoice.com reviews or complaints about CMS Voice should carefully investigate the business before purchasing anything.

Ask the representative to provide the following information in writing:

1. The complete legal name of the company.
2. The company’s physical business address.
3. A detailed description of exactly what will be provided.
4. The total price and whether charges will automatically renew.
5. The cancellation and refund policies.
6. The specific voice-search platforms receiving the submission.
7. Proof that the caller has permission to contact your number.
8. Confirmation of whether the caller is an employee or a third-party telemarketer.

Do not allow a salesperson to pressure you into making an immediate payment. Take time to independently review the website, terms and conditions, cancellation policies and available customer feedback.

What to Do If CMS Voice Calls You

If you receive an unsolicited call from someone claiming to represent Client Marketing Services or CMS Voice, document as much information as possible:

• The date and exact time of the call
• The telephone number shown on your caller ID
• The name used by the representative
• The company name provided
• What product or service was offered
• Whether you previously consented to the call
• Whether you asked the company to stop calling
• Any follow-up calls from different telephone numbers

You can also take screenshots of your call history and save voicemails or written messages connected with the call.

Canadian consumers who believe a telemarketing call violated the Unsolicited Telecommunications Rules may submit a complaint through Canada’s National Do Not Call List. The complaint process generally asks for your telephone number, the caller’s name or number, the date of the call and details about what occurred.

Important Information About Compensation

Consumers should be careful about claims that every National Do Not Call List violation automatically entitles the recipient to thousands of dollars.

In Canada, the CRTC can investigate potential violations and impose administrative monetary penalties. However, filing a National Do Not Call List complaint does not ordinarily create an automatic personal compensation payment to the person who received the call.

Anyone considering a private legal claim should obtain advice based on the applicable laws and the specific circumstances rather than assuming compensation is guaranteed.

Avoid Unsolicited Voice-Search Sales Calls

My recommendation is to avoid making a purchasing decision during an unsolicited CMS Voice sales call. If you are interested in voice-search optimization, conduct your own research and compare the service with established local SEO and business-listing providers.

Do not provide payment information until you fully understand:

• What the company will actually do
• Whether the service duplicates free listings you can manage yourself
• Whether the payment is monthly or annual
• Whether the subscription renews automatically
• How cancellation works
• Whether any promised results are guaranteed

No legitimate company should object to a potential customer taking time to independently investigate an offer.
