accept no substitute My wife and i both have occasional lower back discomfort to the extent of limiting our mobility. There have been numerous occasions (including moving day to our new house) where we would have been bedridden without our hyperice waist packs. We have tried other products but the bottom line is that you usually get what you pay for. We each have a pack and an arsenal of fuel refills in case both of us are stricken simultaneously.

Just caveat emptor in Irvine Calif. Received my Hyperice product, which to-date seems to be working well. The unit is supposed to blue tooth to a Hyperice App. This is just BS!!! (1) After almost a week of writing and calling Co., I still am NOT able to even sign into my account. Hence, I cannot use the App. This company has the most incompetent customer service & NO tech support. WOW!!! I guess its caveat emptor in Irvine Calif.

The best customer service I've experienced in a long time! I had a fault with my Normatec Boots where they weren't charging. I emailed in and got a response very quickly, after a couple of problem solving attempts I asked if they could send out a new charger for me to try as that would be the simplest fix. This was met with an immediate yes and the charger arrived a few days later. Alex kept me up to date every step of the way and was extremely helpful. The best customer service I've experienced in a long time!

Great product and great customer service I've been using the Hypervolt 2 Pro for little over a year & I am very happy with this device. I feel especially refreshed after strenous leg workouts or after sitting down at the office all day. I am also extremely impressed with their customer service: very knowledgeable and fast acting, very nice way to have my issue handled like this. Great product and great customer service. Definetly recommend!

Awesome customer service on my Normatec… Awesome customer service on my Normatec 3. Unable to charge the device for some reason, after a couple of quick mails to customer services showing the serial code and proof of purchase, I was sent a return delivery pre paid postage and within 48hrs of posting, received a new device. Can't ask for more than that with a product that is 18 months old
