I bought 3 pieces.... but one broke in the second year and the electric fan stays open all the time.... it is not justified at this price

I have bought two in the last semester. Very good quality of plastic construction. It has 3 different programs and of course you water from a different valve each time if you want. The only thing that gave me a little trouble is the programming the first time until I understood its philosophy. There is a video on YouTube with step-by-step programming.
You can program 3 presets (A, B, C) if you want to separately control the first or second valve or both together, and separate time for each program.
At its price with two outputs, I highly recommend it.
Update: after 2 years, and after buying a total of 6 but having replaced 3 under warranty. It is not allowed

Good construction with good plastics. Programming requires a little familiarity. Not very difficult of course. It has three programs that you can customize as you like. I recommend it.
P.S: I will deduct one star because you cannot program a separate duration for each station. For example, if you choose 10 minutes in one program, it will be the same for both stations (faucets).
