Query: Buyer Beware - Do NOT buy this junk

This light worked for about 30 seconds, then died. Tried it in 3 different pc's - nada. Contacted the seller and was refunded the $1.51 but I'm still out the $3 shipping.Even if it did work, I would not recommend this light to anyone. It is so heavy that it will strain your usb port and probably break it. If it doesn't break it, it will enlarge the port where it will not make good contact with other devices put in there later. I can't believe this seller is still selling these. I wasn't going to leave feedback at first, thinking he would pull these off the market, but he's obviously satisfied making a few cents off shipping after refunding folks the item price. Shame...
