seems to work well. no noise.
Loud plop when you turn it on. The capacitors are cheap and only 6x 470uF. Traces on PCB are narrow Aluminium radiator only mounted with a small blob of paste. But you get what you pay for, and for the money it's quite good. You can improve things yourself, but it would be nice if it was built a little better for a couple of € more.
