I bought this mat because I have a very slippery bathtub and wanted to make sure that it was safe. The mat sticks for a while when it is dry, but when water is added via shower, the mat slips and doesn't stay in place. If I could have given it a negative star rating I would have. It was inexpensive, so I guess you get what you pay for.
Bottom Line No, I would not recommend this to a friend
