Pros: Great travel size to easily stored away in your carry-on or luggage. On long trips, you can take this mini-massage gun while on a plane or long drives. I tried using my T5 on a 4-hour drive as a passenger, and it's pretty bulky. This would be perfect for tight spaces, and it's easier to hold on while giving yourself or others a massage. The percussion type of massage gun is much better than a regular vibrating for pressure points. It just does a better job releasing the tight muscles. A smaller version is a plus! The flat metal attachment feels really good. Something different from my T5 included accessories. $79 is a competitive price for this mini-massage gun. Also, the noise level is lower than the T5. Very quiet!
Cons: The power is not as strong as the T5 because of the smaller size obviously. Usually, I don't use a higher frequency setting on my T5 because it's enough for me. I don't really consider this a "Con" in my opinion. As much as I like the flat metal attachment, it's cold when you first use it and eventually it warms up. But if you need to start warm, heat up some water first then dip the aluminum tip before a warm massage. I would not recommend heating this in the microwave was some plastic attachments are able to. DON'T DO THIS!
Overall, great product for value, durability, low noise, and compact. I highly recommend it!
