Ticks all the boxes and costs less
AGuita, 07.07.2021
A compact sized PSU with 8 truly isolated outputs with the most commonly used voltages, 2 of them switchable (9/12/18 V) and with enough juice for most pedals. Also brings all the cables you'll need (as you would expect). To put it in a nutshell, it will power all your pedals safely and quietly. What else would you need it for?

My only concern was quality. After researching about Harley Benton in several reviews, I found a consensus of opinion that it is a good quality brand. So far there's nothing that would make me think otherwise.

The choice was then between this PSU, a much more expensive traditional brand or a cheaper brand falsely claiming to be isolated or with dubious quality. It was a no brainer for me! Save your money for some nice pedals.

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

Good value, good product
lwhealsie, 27.07.2021
Overall a good product, very useful and not noisy as other reviews may say. Well built and the variable power is incredibly useful especially if you are in the market for vintage boss pedals and can't be asked to buy the vintage adaptors, as I was.

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
