Review: I was a little worried about whether or not these circuits would work on 3VDC since the title states "3.7 to 12VDC". Connected them to 3VDC (2 AA batteries) and it works flawlessly. I don't need to mess with the different available modes, so I don't know if they work or how hard it is to implement, but the momentary function works perfectly for me.
Review: amazing how small this thing is. works as advertised :)

### ⭐⭐⭐⭐⭐ Review
*by A***T on 24 June 2025*

So one side of the yard I have a pond, the other side is a 24vac valve. I'm using a fill relay which I also purchased on Amazon. The purpose is to fill the water up for the pond automatically. This needed to turn that relay on from about 100 feet; otherwise guess who gets to dig a big trench to run one tiny wire. This is the only product I found like this. The pond side uses 24vdc turns on a buck converter to 12v which turns this on. The other side is a 9vdc psu I had laying around. I will update this review when it fails!
