The Uberbuss is the most cost effective high quality AC cleaner I've used, and I've used a bunch of them. Many here admire them greatly. They will handle massive power without compression- 40 amps, far more than the circuit can provide!
Mine has 3 duplex Pass & Seymour 5362I heavy duty spec grade outlets, and has been used in a low power office system for several years. Fully passive; I don't think there's much to go wrong with these over the long haul.
There is a surface paint scuff and a small paint chip on one lower corner, otherwise excellent (the line showing in the first pic is a cabinet seam). See pics.



I will cover Paypal and shipping to cont. US.
Excellent current delivery and superb sound from the combination, though.
Thanks for having a look!
