doesn't clean glass very well. when glass is thick, these magnetic cleaners need to have strong enough magnets to apply force as it moves. my glass is 10mm thick, and the magnets really aren't strong enough for cleaning glass of this thickness. the product claims to be able to clean glass up to 12mm thick, but if you've got a large aquarium, i'd look else where.

Definitely not strong enough fror 10mm glass

Still falls off extremely easy even with slow movements on my 12mm thick glass tank

The magnet isn't strong enough and it keeps coming apart. It also doesn't clean the glass. Disappointed.
