This is probably the best timer among those in the market. Sadly mine(DIEHL) just failed recently which last me for 1.5 yrs. The first one I used(other brand) failed after a week, flume of smoke coming out from the time which really startled me. I was lucky enough to be at home if not a fire might me started just like that. 2nd time I got the same brand & it failed again on reliability issue! At last I switch to DIEHL though it failed after 1.5 yrs, I still believe that it’s the best timer so far,
so I got DIEHL again! I’m very unlucky to have 3 timers failed within a short period of time, it really hurts my pockets!
All of them cost between $30-$40.
