I had to send back a reference powercenter because the volt meter backlighting went out, They sent me a brand new one the next model up. (mine was discontinued) so really... I bought it really cheap off the internet, it broke, Sent it back and got one thats even better for the cost of return shipping. Saving a few hundred $$ in the process since the one they sent back is much more expensive than the one I had. At least when i bought it.

Pretty good if you ask me.
