## Customer Reviews

### ⭐⭐⭐⭐⭐ It works
*by N***O on November 23, 2024*

Direct drop in replacement

### ⭐ Absolute garbage
*by A***R on November 18, 2024*

Tried these despite not having luck with them in the past, because they were the only thing that would fit in the bilge of my Morgan 364. Lasted about four months and then crapped out. There was obvious corrosion where the wires went into the switch. Don't buy these, it'll just encourage them to keep making this crap instead of engineering a field switch that actually is durable. It's not just Whale either, I worked for a company that installed water witch switches and they were just as bad.

### ⭐⭐⭐⭐⭐ So far more reliable than micro switch
*by B***1 on July 26, 2023*

I am happy with this purchase. So far, the contactless switch has been more reliable than big brand bilge switches that depend on a micro switch lever for turning on and off my bilge pump. My problem with micro switched float levers is they don’t always turn off after the water levels drop. The Whale senses when water is present at the level of where you place the Whale. It works, no moving pieces to worry about. You still need to keep the bilge clean but no longer have to worry about a switch stuck in the on position, draining my battery.
