a handy switch and without power

I had seen my installation previously purchased an electrically powered switch. This one was connected at all times (too complicated to disconnect between uses, and if any advantage over a cable to change). He held 5 years.
I decided to try one without power switch, and frankly it works very well: when I turn on my Home Cinema LED lights and sends the signal to the TV without noticeable loss; and the few times I use my projector I just push the button to switch the signal to the projector.
In short a good value!
The question his behavior over time.
