Query: Don't go near this switch!

I'm an electrician. I've heard nothing but horrible things about this switch a few years back, but I thought maybe there may have been a bad run of them. It's a cool idea! Within 5 minutes it was installed. I worked for all of 10 minutes, then nothing! the transmitter stopped transmitting. Yes, the batteries were new. Simply, it's a Chinese made POS! It's one of those things that's good in theory, but not in practice. Go to the extra distance and pull the 3-way switch cable through the wall. It's reliable and worth it. There are NO FREE LUNCHES!
