I really like this one where you can turn on and off each connected units power, for example my USB hub, wich otherwise always have a little light (led) on, but has no on/off-switch to it...
I used to have the Adam Hall one, but they were called back by the company. It did work for me but there was something with the unit so had to send it back to them. But this unit is just like that one, I bought two for each rack I have in my home studio. For example I can turn on my 3 speakers sitting in the chair instead of going up and reach back behind the speakers to turn them on and off every time.
Have all my Audio Interfaces and other outboard gear and hardware units connected to thesem aswell as printer, USB hub, etc.
Great unit and pretty unexpensive aswell imo!
