I originally had the regular version, it wasnt very good for 1/2 glass. Get the MAX.
Interesting that the manufacturers description states the max should only be used on glass 5/8 or thicker.
"Fl!pper MAX is made with the strongest rare earth magnets optimized for fresh or saltwater aquariums up to 1in (25mm) in thickness and no less than 5/8in (15mm). "
I do have to admit that the regular one I used does feel under power for my 1/2 inch.
