Excellent relay!
I have purchased other 8 channel relays in the past, but they certainly do not compare to this one!! I am using the relay with a raspberry Pi for home automation in my man cave. Controlling items such as curtains and movie screen. The relay has worked flawlessly. Will certainly buy again for future projects.

We've used many of these sainsmart boards to control valves, fans, etc., and they've been a great economical option to interface with National Instruments DAQs.
