Where do they have them? That is incredibly dumb considering they already make things exactly like that--small world . Just trying to get another slice of the pie, I suppose.
I bought a few of the $5 magnet algae scrapers at walmart and superglued them to my powerheads. No more suction cup woes, they hold great, and I guess if my algae ever got bad enough, I could rig my powerheads to become motorized glass cleaners!
