I bought one from Walmart as a Christmas gift for wifey. Right out of the box this is a piece of junk and is a complete and utter waste of time and money. The company that sells this steaming pile of barnyard do-do is Ontek, noted for selling nothing but the worst junk ever. The heat does not heat. The vibrator does not vibrate. The wrap itself is heavy and very uncomfortable with bulges in the internal structure the size of baseballs and feels like you're wearing a string of hand grenades. If you try to lean back, it is very uncomfortable. I have talked to many others who purchased this scam item and have heard of not one person who received a working unit.
If you buy one, you will be SORRY! Save your money! Get a hot water bottle; it will work 1000% better.
Bottom Line: No, I would not recommend this to a friend
