I love this massage gun! I’ve purchased a LOT of massage devices and pain relief/recovery tools and gadgets (including two other percussion guns) over the years to help manage a connective tissue disorder with intense muscle spasms. Not all of my purchases have worked out. I'm happy to say the Sonic Pro is the real deal--and at a surprisingly low price. This kind of percussion is particularly helpful with my myofascial and muscle pains.Before discovering Lifepro, I had borrowed a friend's more expensive massage gun (she paid more than 3X the price for a competing brand.) I like everything about my Sonic Pro so much better!! It’s easier to hold onto with a non-slip grip handle. It comes in a compact storage case with an impressive selection of easily interchangeable heads, although I’ve settled on mostly two or three of my own favorites for targeted relief. And it’s the quietest massage gun I’ve tried, without sacrificing the power of more expensive models. The Sonic Pro is intense enough for my roommate’s thick “soccer muscles” and my own super spasms (My chiropractor jokes that I'm the "woman of steel!") but its lower settings are still effective for more tender areas. I like the wider range of 15 incremental settings--instead of just high/medium/low--and the digital timer function. Tip: besides adjusting power or pressure, changing the massage heads can alter perceived intensity. We took turns using it pretty regularly every day for five days before it needed to be recharged. The only thing I would probably change is the “beep” when you adjust the settings.I did a lot of research before choosing Lifepro. With so many competing products on the market, it’s really hard to tell them apart from just pictures. I've purchased several other health and wellness items from Lifepro and have been truly impressed with my products and the way Lifepro actively supports them. Right out of the box I could tell the Sonic Pro is another quality product, and it has exceeded my expectations so far.
