I have 7 of these that work perfect, and one that works, but the laser never shuts off. You guys inspired me to test them all. I changed out the cords with a couple of extras so they ALL have a ps2 keyboard cable. And the cable has a pass through in case you need to plug in a keyboard.

I'm really learning a bunch from you guys! Since the link I saw on ebay was selling these for $20-25, I'll offer the 7 working ones for $10 each, and the one that doesn't shut off for $5. Plus shipping. Actual shipping cost based on weight. PM me and I'll send you my Paypal link.

I'm glad you guys suggested I test these out. I had to pull out an old laptop with a keyboard port, but I'm sure there are usb adapters.
