I had two. At first glance, they seem to be sturdy construction. I had one to turn off the Soundbar when the TV is turned off and the second one to turn off screens/speakers/hubs when the computer is turned off. The first one simply stopped working after about a year. The second one started tripping my circuit breakers. It was confirmed as the circuit breaker in my office was tripping 2-3 times a day. As soon as I removed it, it didn't trip again. I put it back in, and the tripping happened again. So, not only "wasted money" but also dangerous.
