OK but somewhat noisy
georgebranekov, 12.10.2020
Bought this unit to accomodate more pedals, including some digital quite hungry ones. While it powers everything just fine and there is no lack of power, it is somewhat noisy and "sounds" dirty. Definitely some noise goes through and as a result you get a suckier tone. Tried removing pedals from the chain and changing cables and wall sockets, problem leads always back to the power unit. I am dissapointed, although if you play in a place where electric installation is perfect maybe won't be so much of a problem. I switched back to the Harley Benton Junior brick, which works perfectly well and there is no noise whatsoever, and for the hungriest digital pedal just opted for a Boss wall adapter. Done, no noise. I wrote in my HB Junior review that if I needed more power, I would get a second one - I wish I did instead of buying the ISO-2 Pro.

Probably all the power you'll ever need
albertotp, 20.05.2019
It's incredible what they achieved with this design, including many features of more expensive products in a relatively compact format and for a decent price. Quality-wise I cannot complain about it and I had no issues and no noise powering 6-7 pedals including digital tuner, modulation, looper, and using 12V and 18V options.
Many other reviews already mentioned that the power adapter could be more robust. Other thing is that all DC cables have 1 straight and 1 angled connection, which may not fit everyone's need. All DC cables have the same length and are too long, which is better than being too short, but for small boards plenty of cable management is required. I had to buy 2 additional short DC cables for it.

I've made a full review and isolation test here: youtu.be/NZqCcpu81rY

I've also managed to fit it under the Spaceship 50c by making slight modifications to the board: youtu.be/h8Lkg5a4ahg

Excellent power plant for pedals
H. Gabor, 19.07.2020
I bought this unit for my pedal board.

It's a very well designed power plant for an ubelievably reasonable price. It's small, practical, durable, good-looking, reliable. Adapter and a set of plugs are included that is a big pro. With eight outputs plus daisy chain possibilities, it can supply a whole pedalboard. In my experience It works without adding up extra noise.

The two adjustable outputs can be very useful. For example I have an old Boss pedal, still usable, that requires 12V when it runs on an adapter and not on battery. With this powerplant I could easily organise that old pedal into my signal chain containing more modern units with 9V power supply.

Cons: The adapter looks a bit vulnerable, particularly its cable. I guess it should be a bit more heavy duty unit for travelling or working on stage.

I definitely recommend it.
