Bought this as a primary power source for my rack consisting of a PC, an X32 and a Kemper. It has always been reliable since the beginning and it's still working perfectly fine after almost a year.
Anyway this power plug / voltage meter has also 2 downsides.
the first is that the power cable isn't detachable, so you're stuck with the one provided which can be too short or to long, like in my case.
It's also a schuko plug, so the european standard but also the bigger plug format, very expensive in terms of space.
The 2nd downside is the quality of the elements. The LEDs of the voltage-meter are very cheap, also, the two lights are halogen and not LED lights, this create high temperatures in case of prolongued use of the lights, also it make extremely hard to find replacement bulbs for those lights.
Don't panic, as said before the product still works perfectly fine after almost 1 year, so i guess the quality of those components is enough, even if those are cheap. Definitely best bang for the bucks.
