Best Magnet Scraper for Glass

[SPS2020]

Holy smoke batman! Anywhere from $150 up to $1,500 for a magnet cleaner! Are the things made of gold, perhaps some platinum?

Someones smoking the good stuff at that company.

I'm in for about $350 (FF4), but it is too much magnet for my tank. I wished I had gotten the next model down. This thing has crazy power. Their different pads are unique and really remove algae quickly.
