Question: This is easy to use and comfortable. The heat doesn’t last that long and the scented smell is so terrible that I can’t even keep the eye mask on that long.

Answer: negative


Question: Bought this after reading good reviews. But it’s not water proof at all. If my son has even a little accident in bed, it goes straight to mattress. I don’t see a point in having this. So I have to purchase another one.

Answer: negative


Question: This set was a positive surprise. Products work as advertised. Foam roller is firm and good quality. Massage stick is my favorite from this set, easy to relieve tightness from leg muscles, works great. Massage ball I use mostly to my back, shoulders and neck. I was a bit hesitating to buy this set because of the low price and from my experience low price means bad products. That was not the case here.

Answer:
positive
