Pros - Inexpensive
Cons - Not very accurate timing adjustment in the shortest duration adjustments. The minimum is about 1 second and then turning the pot quite a ways causes the timing to go to a 35 second delay. No adjustment in between 1 and 35 seconds. I bought two of them and they both have the same issue. My needs are around 5 seconds delay. Seems to work fine for longer delay periods but poor adjustment at the lower end of the range. Ended up purchasing a different brand timer that works very well.
this was just the cure i needed for a thermostat that was jumpy on start for the ice machine.
gives it time to make up its mind. even though it doesnt have one.
