## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy install, lifetime(?) warranty
*by D***T on September 6, 2018*

This is a sturdy switch that will end my semi-annual replacement of bilge switches. I hope. The technology is simple and worked in clean water in my tests. It successfully drains my oily bilge to about 1/2" with a Rule pump and hasn't failed in 5 months.Note that others have said that the company is a stickler for rules for the warranty. I returned the card by post (??? what century is it??) AND kept a copy on my phone. I also used the indicated connectors high and dry in the bilge, though I would rather have soldered them. One plus I didn't see in the description is a green LED that tells me the unit is powered and ready to pump when necessary. Of course I'll be checking my bilge less often with this beauty in place...

### ⭐⭐⭐⭐⭐ Good Product
*by D***D on June 5, 2021*

Good quality product with added safety benefits. Good installation instructions.

### ⭐⭐⭐⭐⭐ Great Pump Switch
*by W***A on October 29, 2013*

This is the best and most reliable pump switch I have found. A friend who is a harbor pilot and owns a boat yard recommended it to me. I am on my second sailboat and I just installed my 2nd "Ultra Safety Systems Pump Switch Sr." and I never had a problem in the 11 years I had my first switch. The typical bilge float switch can hang up leaving your pump running constantly. That is what happened on my 2nd sailboat and today I installed my new one. I sincerely do not believe you can find a more trouble free pump switch.
