Basically, I was very skeptical when buying, how much you Quality because get for the price, so I could no longer be great disappointment.
The installation and connection of my switchable components was possible without any problems, even if the space for clamping is quite limited and you have to strip the cable is relatively short. Actually, a no-go, though, is that it lights up when the circuit is turned off and vice versa, the indicator light does not burn, when the circuit is switched.
On the other hand, I'll accept the shortcomings for the price and the effort demonitieren everything again and dispense to return. I'm even willing to forgive 3 stars for this price / performance because the actual on / off switch and mounting works perfectly.
