Rated 3.8 out of 5 by 4 reviewers.
Rated 2 out of 5 by Unable to bypass without removing timer screws. I needed a 220v sprinkler timer. Home depot or Lowes does not have one available at the time of this writing. I needed one with a day skipper and rain sensor. This is just a 24 hr timer. I had to comprise for now. If you are stuck like me then this is pretty much the only choice. I am not happy with what was available to me. I had to go to the electrical side to find this. October 14, 2014
Rated 3 out of 5 by Good mechanical timer Mechanical switches are easy to install and set. I would give it 5 stars but the ON throws cannot be overridden with a manual shut off - you must remove them or trip a breaker. June 17, 2014
Rated 5 out of 5 by great pool timer very satisfied. used for timer on my Polaris pool cleaner. January 14, 2014
Rated 5 out of 5 by Same timer for 40 years For those of you looking to just switch out the guts, this is the one to buy. In ten minutes we had the old timer out and the new one in. It looks, fits and works like the original. Single item keeping it from being 5 stars on quality is the timer tabs are still a little loosey-goosey, be sure to tighten them down well.
