Review: has been used for two years - got this almost 2 years ago to remote control my garage door so far, has been working great. recommend it if you're handy - btw, you can control it via Google Home, so now my old garage door is remote controlled. lovely
Review: Dual relay works great - I had a single relay version , this one is a dual that runs off of 5-48 vcd , read the pairing instructions, I have several ewelink devices and was setting it up as I did them. , don’t do that. Really easy if you read instructions. Dual relays that operate individually .great for hobbies. Fair priced.

### ⭐⭐⭐⭐ Nice product. Well built. But, there's a problem.
*by W***S on November 30, 2025*

The rating is mostly for the board. The 5th star would have been for the app. The hardware looks well done. What isn't good about it as a system is the app. It is a blatant opportunity to copy what's on your phone. What does a switch need with my personal info, photos, videos, and other non-requisite items to control a SWITCH? If I cannot find an app that doesn't do that, I'll return it. But, hey, if you don't care, go for it.
