Review on TORCHSTAR Flexible Waterproof Decoration Commercial Lighting & Ceiling Fans by Travis Showcase

To the seller: I've just discovered that this item is defective, but it's a day after Amazon's returns window closed. The fuses are blown. After the first fuse blew I decided to order more fuses instead of returning them because I think that's exactly what I want (it worked for a few minutes before the first fuse blew). But now every fuse I plug in blows instantly. I can't believe I missed the return window by a day. Can you advise me what to do? I will not rate this launch until this issue is resolved or not.
