One of these red little devils is powering my main bass board, while the other is going into my main guitar board as another (secondary) juice spender. The price is just right for the quality. Well build, sturdy casing, compact enough to ride on beneath any pedal board or even on top of a big board with extra space.
The isolation works, I have detected no extra noise from any of the ports. If being real nitpicky, the only downside is that it does only 9V and 120 MA per port, but this should cater for all your basic needs and anything but the most power hungry pedals. (Check your digital delays and such before buying, though.)
I'm loving these. May order yet another one in the future.
