Query: Do not buy this item

I recieved this item from my husband for Christmas. One month later the heat and vibration feature would not work. Amazon replaced the item immediately. I have had the replacement for three months and it has now started leaking. Not just a small leak- pouring water all over my hardwood floors!!!! I am now trying to return the replacment but the time allowed has expired. Apparently the expiration date was three days before I reveiced the replacement- are you kidding??. I am now stuck with this item that obviously has issues and I cannot receive a refund for it. I am very disappointed in the quality of this product and Amazon. I would expect the "return period" to start AFTER I receive the replacement. This was not one of these products that had problems but two in a four month period.
