It's great for the money
deusem, 20.04.2021
I wanted an isolated power supply, but the price has always put me off, I mean for almost 200 euros I prefered to buy something flashier like a fuzz or a delay pedal. Well, this one does the iso thing, and it costs so much less money than the average psu so it's a safe bet to see why an iso is better. Long story short, no more noise, buzz, and possibly no need for a noise suppressor pedal (unless you re in very high gain).
So the "negatives" comes from the fact that I had a valve preamp pedal that needed atleast 600 amps to operate, so I used a doubler cable to use two of the sockets (500 amp each). It did work, but took some time to operate, and according to the preamp manufacturer the current was not enough. I tried it with a different psu (more expensive) and had no issue . So I assume it's not the best quality, but for one pedal at a time, I can't tell the difference

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

So Far so good
Tomtsa, 02.02.2021
I chose this because it is way cheaper than similar options with similar features. I had it for one month and so far I have no complaints whastoever. I does what it says it does and it is way cheaper than similar options around.
Sometimes with power supplies I'm like... how can it be that expensive if it is 20th century technology ???

Low profile and works like it should
AmazingAlien, 04.05.2021
This thing just works, plain and simple. It's pretty low profile so should fit under your board. Quality is top-notch, no hum or weird noises, cables stay put, ... perfect!
