Bad experience requires wise decisions
This device is top of the line, at least that is my experience. Though recently I had some problems when at the same time a 2000 GPH pump failed within two months of use even though it has a four years warranty. Amazon Rep told me that I would need to contact the manufacturer because my time warranty through Amazon would be only 30 days and from then on...I would need to contact the manufacturer. ( somewhere in China ) I understand Amazon policy, but honestly I expected more from this Co. And then it occurred that a cheap float switch failed 48 hours after installation. But it happens that the cost of installation is at least three times the cost of the device. So, I decided to go for RULE....to be on the safe side. This is my recommendation. to whoever needsto replace a damaged float switch that are always located as deep and unaccesible as the boat builder could install them....

Easy to use
Very easy to install and to power. Very fast to activate pump. Installed it in my bilge area and has not failed me

Works as intended
Seems to work well. Would prefer if it turned on a bit sooner and was a pain to install on my boat, but that was not an issue with the pump. It is great that you can attach to your hull then snap in place. A product that you hope always works in an emergency.

Feels solid and well made.
I have not yet installed it but the switch feels solid clicks so should be reliable, the hinge feels quality, small enough to fit almost everywhere. Vires are marine grade. Would buy again.

Best if normally kept dry.
8 Years so far. has worked very well. The trick to longevity is to place in a dry location. The float should trigger only as unusual water level is encountered. bolting it to the lowest point of the bilge where it will be forever submerged is probably the reason many are failing so early. Default to a location that indicates high water without needing to be wet all the time, and this will last many years. A small shim below giving some clearance from normal bilge height will go a long way.
