Query: This WAS a good product

I replaced the first unit because it did not weather the winter - it froze and broke. The second unit stopped timing and the timer mechanism was sporadic. Sometimes it did work. The replacement for this unit (within the first year of use) has a different, less defined time dial that does not allow for fewer minutes and I found the housing was cracked the first time I used it. I will return it and will be looking for a different brand of mechanical timer.
