Independent Reviews & Red Flags
Scam Allegations
Numerous reviewers have expressed concern about the product being fraudulent or false:
A look at an item marketed by the name of “Solymall Cooling Ace” found it to be low-cost Chinese plastic that boasts over-inflated claims, pointing out flawed marketing strategies as well as patents that are not in use, and poor customer service
YouTube videos with the title “Mamolys Cooling Ace Review – Legit Or Scam? DETECTED!” and others describe it as “just a fan, not an cooling system” with complaints regarding the noise, cooling performance, and customer service
User Experience Insights
Airflow is often weak, which can be disappointing when compared with windows or central AC.
Noise levels may exceed 20 dB; users say “white noise” or louder.
The cooling effect is comparatively localized. It doesn’t make a room feel cold immediately.
The feel of the design is cheap. Plastic housing, thin buttons.
Customer support is usually not responsive when refund issues are reported.
The absence of credible reviews doesn’t support the extreme cooling claims; in fact they’re frequently disproved in independent tests or YouTube reviews .
YouTube Analysis
I came across several recent YouTube reviews. The most relevant was:
The reviewers in these reviews highlight:
The marketing hype is that it’s a “bladeless air conditioner” but in reality, it’s an evaporative fan that is small in size.
The sound level is greater than stated. However, users do not specify the level of whisper.
Cooling impacts are very light–a mild breeze with a small drop in temperature.
Customer service was not satisfactory and there were no the return policy.
Technical Breakdown …….
Evaporative vs Compressor Cooling
Evaporative coolers (like these) make use of water-soaked filters and fans. They aren’t able to reduce the temperature of a room to below ambient temperatures as long as humidity is not low. The claims of “cools rooms by 30 degrees Celsius in a matter of seconds” aren’t realistically possible for a portable 10 W device.
Compressor ACs effectively condense and eliminate heat, making them far more efficient and energy-intensive.
The Mamolys model is a miniature personal fan with a slight cooling effect via the process of evaporation. Tests in the real world confirm that the cooling and airflow are not that great.
Summary of Real-World Pros & Cons
Positives:
Compact, lightweight–great for desk or bedside use.
USB-powered–versatile and convenient.
Multiple fan speeds suit different preferences.
Secure bladeless design that has no exposed blades.
It may be quieter at lower speeds, but not as quiet as advertised.
Negatives:
Marketing overhype–mislabelled as AC with dramatic temperature claims.
There is a very weak breeze that barely reaches larger rooms.
Louder than the 10-20 dB claim.
Cheap build quality–feels fragile plastic.
Refunds and questions about after-sales support are not always clear. lack of reliable support.
Limited cooling, only suitable for personal 1×1 feet space.
Ideal Scenarios & Alternatives
Best Use Cases:
Personal use for small amounts (e.g. behind of your face when working).
USB-compatible configurations are great for laptops and desktops.
A secondary device that is used in conjunction with traditional cooling (like central AC).
When to Avoid:
If you’re expecting room-level cooling, or “real AC” results, you’re not getting it.
The build quality could fail.
Depend on the support of your customers.
Better Alternatives:
Small evaporative coolers equipped with real tanks (Champion Breeze, etc.)
The Budget Window or the portable AC models (BTU-based)–far more efficient even if they’re power hungry
Good USB fans, no evaporative tricks however, they will provide consistent airflow
Final Verdict
The Mamolys Cooling Ace is useful as a desk fan, which provides basic cooling by evaporate. With a price of Rs3,500-5,500 ($40-70) the price is in the middle of the market for gadgets that are niche, appealing to people who need something lightweight and powered by USB.
However, the claims of marketing like “instant 20 degrees of cooling” “room-chilling cooling in a matter of seconds,” and “20 dB whisper-quiet” are inflated and misinformed. Testers and independent reviewers call it what it is: a personal fan, or at the very least a moderate cooling by evaporative.
Recommendation:
You should buy if you want an inexpensive, portable air conditioner for your personal needs, and know its limitations.
Do not buy if you are looking for genuine room temperature, a solid design or dependable customer service.
Buying Tips
Check the branding and seller’s details. There are lots of OEM variants.
Review user reviews at Amazon or YouTube to find the exact model you’re looking at.
It’s important to understand that it’s evaporative and not compressor tech.
Set realistic expectations. The focus is on the micro-space that is closest to you, not the whole room.
Plan for alternative options If you require a lot of cooling (BTU AC, high-quality desk fan, etc. ).
Conclusion
The Mamolys Cooling Ace exemplifies modern impulse devices, which are compact, stylish and a lot of hyped. In reality the device is a low-level element that cools the summer, and not the replacement for an air conditioning. If you align your expectations–portable, minor cooling, USB convenience–it can be a fun desktop accessory. But don’t expect miracles.
