Little cheaper and WAY smaller and stronger than those. It's about the same dimensions as a 9mm bullet for comparison, and only 4mm thick. Sticks on my 3/4" glass without a hitch on the Ocean wonders frag rack.. I also use these replacement magnets for my ato float valve in my sump so you know I trust it.

+1, these are some of what I use. If I need bigger, I make them myself. By earth strong and encapsulate them with acrylic. Not fancy but they really work!
