Good product

Works as expected for what I needed for my pool while doing maintenance on the salt cell. A little pricy for what it is but nevertheless needed it.

It's a plug, it plugs.

It does what it's supposed to do.

Works for me

Easy install. Used it to plug up our water return line to our above ground pool. Pulled the "eyeball" out & installed this. Does what it says. Just make sure to coat the rubber o-ring w/ a Lil o-ring grease before installing.

Worked good. Picture is deceiving. Only 1 plug

Thought I'd be getting two of them from the picture but it's only 1. Works great though
