I've sent the unit back to be repaired after a year of its purchase - the power button (felt flimsy anyway) failed and the unit wouldn't turn on. Thomann fixed it - worked for about 6 months only for it to happen again, even after turning it off every 2 or 3 days.
There is no way of powering on the unit once it's been turned off other than in barbaric ways aka shaking it or the good old American slap-on-it so I keep it on at all times. It makes the unwarned power outages a real threat it not to mention to my whole system if it won't turn on again (the power of my hits to its top need to increase each time in order to turn it on) - the local power (distribution) company managed to spike out my previous monitors, a hard drive and half of my sound card due to its notorious voltage jumps.
Another issue is that a low buzz-like hum is getting louder and louder (which also existed on the first day of its operation), coming from where the fuse is. It's still low and can only be heard when there are no other noises but if for example I move my PC (or other rack gear connected to the PL-8C E), even by a centimeter, it goes to irritating levels with an added constant booming tone and I have to adjust the PC case to find a sweet spot for it to disappear.
It does its job well - everything works better since I use it; less noise in the system and the pull-out lights are really cool (the dimmer is also very flimsy) and I'm glad I purchased it if it weren't for this nuisance. If only Furman has/had a stronger quality control, since I've read the same issue happening with (especially) this model. So be advised.
