I use it for a year. The first I received was defective: hum, then quickly, she no longer worked. After exchange standard, the new has worked beyond my expectations: no buzz, it fuels without regard my entire pedalboard which certainly includes only the 9V, but has strong consumer digital pedals (including Timeline Strymon). The other pedals, consume less, are fed through strings without problems. Small switches used to select the output voltage (9 to 18V), but I do not need. Finally, the box is filled with various cables, sizes and colors, more than reason.

It replaces a Fuel Tank Classic buzzit that when I plugged the pedal power demand.
Finally, an excellent choice for a small power, which fits nicely in a pedalboard. I only regret one on / off switch.

Note also that it tends to heat up a lot, but so far, I have no problems during sessions that last long enough (more than 8 hours).
