Heating Pad company, KAZ "SoftHeat"

I purchased a heating pad...controls didn't work, some sort of 'short' in it. Took it back...second one, same thing...third one, SAME THING, fourth one, last one went in the trash!! All of them within a 5 month period. Contacted them by e-mail. They didn't want to do anything about it (of course) by saying I probably "misused" the product...How can a person do that when it doesn't work from day one? Then, they wanted me to send a twenty dollar item to them AT MY EXPENSE for a DEFECTIVE ITEM!! No way...Now I see the wrappers in the stores have the same box, same pictures, but there is a tiny little starburst that says, "NEW"...well, Obviously they knew of the problem and did nothing about it like a recall or anything along those lines. Their product is crap...don't waste your money! My experience, my opinion.
