Ok, I was very interested in this item, because the price is very attractive. I compared it to my MXR ISO-Brick and its build quality, materials, components, soldering, wires are even better than in MXR, but if we are talking about it as a power supply, it's just a noisy piece of power :)
I tested it with several analogue and digital pedals (Bogner, Empress, Tech21, Way Huge, TC...) and there are always some hum, buzzing and clicks. MXR ISO-Brick and separate Line6 power supplies are dead quite. So there is unfortunately no miracle.
