I ordered through a 3rd party dealer & had issues with it, I reached out to LifePro. They were not only apologetic, but after I sent them a brief video, I was shipped a replacement within a couple of days that works like a dream. I was told by my doctor to build muscle mass & improve balance, as I am a fall risk. I placed my Rumbler infront of my exercise bike & hold the handlebars of the bike if needed, when I feel my balance a bit off. The plate runs either manually, or on 3 different preset cycles. I switch through those 10 minutes cycles, that move through different levels & a combo of the different vibrations. On average, I burn about 60 calories per session - do that a couple times in the am & pm - you’ve accomplished a great workout. I am very glad I made the decision to purchase this LifePro Rumbler. Not only for the health benefits, but also because of the company behind it. They’re top notch, which is a rarity today. Thank you LifePro.
