## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product
*by K***E on August 13, 2025*

Works great. Easy to install.

### ⭐⭐⭐⭐⭐ Solid hard shutoff
*by A***E on September 15, 2025*

I bought this shutoff for my boat and it works great as a main shutoff for all of the electronics.The click moving it to on and off feels very sturdy, and it came at a competitive price.One thing to note are the terminal screws are very large so expect to get some bigger connectors, but that's to be expected with how much power can be drawn through it.Also the switch only turns 90 degrees, not a problem, but at a glance that's not obvious.

### ⭐⭐⭐⭐⭐ Great switch for boat battery; needs a 2" hole saw for rear panel mount
*by A***. on July 21, 2025*

Great on/off switch for our pontoon battery box. You will need a 2" hole-saw for the rear panel mounting method. I also used a bead of silicone adhesive around the hole ring to make sure water doesn't get in.Lastly, I ended up having to dremel off the ends of the 4 mounting screws, because they are too long and hit the battery - and stopped the battery lid from fully seating.Overall the switch works as it should. Just be aware you may have to modify your battery box and cut off the screws to make it fit properly for a rear-mount.
