I use two controllers to adjust the lighting of the lighting of two aquariums. Compared to the other programmer model I use, this model has the advantage of being easily programmable, no need to dive back in the instructions to change the time slots. The downside perhaps: it is possible to inadvertently disable the programming mode. This happened to me several times in the beginning, by manipulating the near sockets of the programmer to disable it. Since I pay attention and it's not a problem. And my other programmer model, if it never happened to me disable it by mistake, it is instead a real headache every time I wish to reprogram the ...
So in the end, I think it IDK programmer is a good product, I do not regret my purchase.
Strong point: - Ease of programming. Weak point, if you had to find one: - A little cumbersome.
