I have been using it for about 4 months now, with a Toms Aqualifter pump. The sensors need to be wiped every month or two, I have had tow situations where the water was below both sensors and the controller thought the sensors were in the water. Just a quick wipe with a paper towel once a month is easy enough though. Looks great, and allows you to be dialed in within a half of an inch, which is great for my skimmer...
