Not the best
I ordered this because i saw it's programmable but, oh surprise, you have to create a program in order to use it and there's no way to use it manually, of course you can "bypass it but after a while the thing goes to the program. Second thing is that the instructions are confusing and be aware that the device has one sticker in the back that shows the wiring while the actual instructions show another wiring diagram. It's a pain since the quality of the product is very good.
