Query: Buyer Beware

I bought this as a gift for my husband - it was on his Amazon wish list. However, upon checking, he said that it's part of a kit and they no longer make the other components, so it's basicly useless. There was also no invoice included with the product when it arrived. I've been trying to return the item to the manufacturer but they refuse to reply to my inquiries, so I'm likely out the $160 and am extremely disappointed.
