Query: Good technology but poor execution

I love technology so bought this Timer to help manage our back yard/garden. There are two significant problems. First - programming it is not in any way user friendly. Second - once it is hooked to a faucet (my faucets are just a couple of feet above the ground) it is basically impossible to see the screen let alone try to reprogram it. I sent it back and got the one with the big mechanical knobs and large LCD screen. Will see how that works.
