Unit works great when working... It lasted a bit over a year - bought Dec 2013 lasted until June of 2017. Works better than the traditional float that seems to get hung up (sometimes down, sometimes up) but when it died , no way to jiggle to see if it'll free up. Going under the pit cover today to do what I can.

I have a few of these units, they all work fairly well, sometimes the float gets stuck. If anything grows on the float shaft, it will stick.

I am not terribly fond of the switching delay time. I will likely open the unit and modify the electronics to change this. (I am an electronics engineer, I would not recommend this for normal users.) To clarify, float is triggered, unit runs pump for set amount of time. That time is a bit too short for my liking. I am using medium sized sumps, as well.

We have a very active sump pump. About once every one to two years our sump pump switch used to go bad, while the pump was fine. We ordered the replacement switch from the sump pump company and installed it. Eventually though, the switch housing "screws" would make it so the switch could not be replaced causing the need for a full new pump. Replacing this switch when it could be done required taking the pump out of the pit, disassembling it, installing the new switch and then reinstalling the pump. Replacing the pump could be less effort if all of the fitting till worked.

By comparison, replacing this switch takes under 10 minutes. It does go bad but the cost of a bad switch is the 10 minutes to replace and whatever the price of the switch is, which I believe is still under $40.

When we have a bunch of snow (2 to 3 ft.) and get a warm rainy spell our basement gets wet from a hole in the foundation. I tried other float switches that turned on, but didn't fall far enough to shut itself off. It sucked but we didn't get water damage. This Basement Watchdog switch is bomb! It mounted excellent right where I wanted it. It has a switch on top of a switch so protection is redundant -- if one sticks the other catches water before it gets into flooring. If you're smart, top it off with the Glentronics water alarm. With the alarm, if the power's out or pump isn't working the alarm tells me before anything gets wet.

The timer is not 10 seconds. It's closer to 6, and so our basin always stays half-full. Not really a big deal, but you should not count on it to stay on for 10 seconds after the lever goes down.
