IceCap Magnet Mount Float Valve

With the IceCap name on it i figured it would be a better product. i agree with other reviewers that the magnets are too weak for a strong hold. the float can easily be moved with the slightest bump. also, the bracket is not wide enough to fit over a rimmed 29 gal aquarium which is what i use for a sump. no where in the advertising does it state that it only works with acrylic sumps or rimless tanks. many reviewers have also claimed float doesn't stop water from coming in. i haven't yet got to use it so can't verify that but has been reported by many. if float wasn't already mounted in sump, and i knew i didn't have to pay return shipping cost, i would return it.
