Well colour me surprised. I was sceptical when I purchased this massager. I ordered the foot massager and this hand held cordless massager and guess which one I sent back? The foot massager was an underwhelming experience so bye bye, but this little massager is oh so powerful and has really helped me with ongoing pain in calves, neck, shoulders, lower back, .... I do use it in combination with chiropractor and myotherapist. It is easy to use, the battery life is amazing (I can use it for a few days without having to recharge) and you can adjust the power setting and use different massage heads. I was hesitating between a massage gun and this item and I am really glad I chose this one. I even sent my best friend one as a gift. I would definitely recommend and repurchase. Thank you.
