Bought this as an alternative to the Palmer and Cioks units I am already using on other pedalboards. I have some hungrier units (Meris, Strymon, Digitech JamMan Stereo) and Palmer couldn't really cut it and the Cioks was just a tad under to power the JamMan properly, so I got the VL PP X4. It's spot-on for my needs, runs quiet and stable power, the unit itself is sturdy and small. I'll be getting another one for an acoustic pedalboard pretty soon.
