The listing, Butterfly Labs 5 GH/s Bitcoin Miner BF0005G ~^* Want Some Bitcoins??? *^~ has ended.
I originally got this rig to mine Bitcoins, my computer stopped working because of power supply problems. I can't hook this up to my cell phone so my loss your gain.
USB miners (most I have seen on listia anyway) run at 330 MH/s. This miner being offered works at 5 GH/s which is 5000 MH/s, that is more then 15 times faster then a USB block erupter or like running a little over 15 USB block erupters.
If your not sure what this is or how to use this tool you can look at

This unit is 275.00 new.
Comes with original packaging power supply and USB, very easy to use. Plug in, drivers install and read simple instructions. Unit works great, I tested it out on a friends computer and it works perfect, well over 5 GH/s most of the time.
