[Q]: I bought the 3 pack and had no issue with the first 2. Went to use the third and it is NOT the same and didn't seal off the water. Waste of money. Only OEM for me from now on
[A]: negative

[Q]: Love ur products but this one is NOT good. This photo is 8 hours after class. I've had this mat about a month and the stains never completely disappear. I'm a woman and I do sweat but it's embarrassing to see the outline of my body at the end of class...to the point where people start staring at my mat and at me. Yuck. Please let me return for refund if possible.
[A]: negative

[Q]: Bought 2; they both died two after opening them. Tried to recharge batteries but screws in the units are so small that no screw driver could loosen them. not worth the effort to even return them.
[A]:
negative
