Warranty is through Butterfly Labs. According to their web site, all ASIC miners have a lifetime warranty. This warranty is issued to the ASIC device, not the owner, so I do not warrant the device personally. It is currently running and doing great. I have had no problems with the unit. It just works!

Warranty: This unit's system board has a lifetime warranty from manufacture defect or component failure. All repairs, returns, exchanges will be made through Butterfly Labs, seller is not responsible, and buyer agrees to these terms upon purchasing item.

I can demo the units and show you that they're working over Skype or FaceTime.
