Review on Universal Ceiling Fan Control - Litex WCI-100 Wall Command with Full Range Dimmer and Three Speeds by Delos Rodeo

I installed Litex WCI-100 for my fan. Unfortunately I had an issue where after a few months the Litex seemed too short (or there was a shorted wire which I didn't see) where there was voltage on the switch chassis (and a screw for the cover). So I got this switch hoping it would work. The Litex WCI-100 has five mini switches in the row of DIP switches, while this one has four (I think the extra switch on the Litex was called DP? I don't know what it's for. The other 4 switches were numbered the same as this one Anyway, when I replaced the Litex with this switch, it worked fine and there was no voltage left on the chassis (thank goodness).
