I use this PDU mounted at the top of my rack.
When I first got it, it was DOA. I had to return to Thomann for repair. The process was very easy and quick. Kudos!
The new/repaired unit has had no problems. I use it as a main power switch for the rack mounted units.
The only negative part is that the lights, which are incandescent, gets hot. I recommend trying to replace the lamps if this bother you. I expect later models will have LEDs.
A note: In my country, Sweden, the base voltage is 230V, but there is no mark for that. The LEDs indication is a bit "off" since the scale does not fit the LEDs values. So I would say the LED is a gimmick, and nothing you can use for measuring the voltage.
(aslo, the LEDs are very bright)
