I used this module to replace a mechanical relay module from Sainsmart for my Xmas light display outside. The mechanical relays didn't last long last year. So far this year the solid state relays are giving me no troubles. One thing to note however, mechanical relays can typically handle 10 Amps each. These solid state relays can only handle up to 2 Amps each ... enough power for approximately 100 LED lights on each relay, or 800 total lights per relay module. More than enough to dazzle (or cheese-off) the neighbors! No complaints about this board.
Update: Well, it's a few days past Xmas and not a single problem from any of the SSRs. I love that I can program the outlets to turn on and off at less than 25ms (the limit I found for mechanical relays). This allows twinkling effects that I couldn't do with mechanical relays. I'm purchasing another one for a 16 channel setup and adding a San Devices e682 to the mix for RGB LED control as well (my neighbors will REALLY love me next year). I use an Arduino Uno to control the relays however any microntroller with at least 8 digital outputs will work well with this relay board.
Update #2: I've redesigned my board to use two of these SSR boards for 16 outputs with an Arduino Uno. Works fantastic!
