Bests & Worsts Reviews from Amazon

I bought this product and I like it very much. It massages the leg and foot well and heats the knees. Unfortunately about a month after buying it, I ran into problem with the remote. When I turn on the heat, it shuts down the whole system. So I notified the merchant with video of what was happening. The merchant responded promptly with an excellent customer service and though it was past the return period, the merchants sent me a new unit and let me have the old unit that I can still use without the knee heating part. I greatly appreciate how the merchant, FIT KING reacted to my request and handled the situation. As an engineer, I perfectly understand that merchants don't have control over the manufacturing/production of items they carry and sell but they do nevertheless have control over their customer service. Just because an item is great does not guarantee that it won't have a defect. So without any reservation I give 5 stars + to FIT KING.
