The AF Ultra looks identical to my larger mag float with the slide on blade. A very long lasting design and always did a great job, but I moved to a flipper max edge because I needed the larger area (mostly laziness for scraping algae).
That was hard for me to watch. I cringed every time he got next to the silicone. That scrapper was coming so fast and hard at the silicone. These magnet scrappers are strong Enough to get under the edge of the silicone. Making the silicone bond weaker. Take extreme caution when using the strong magnet scrapers around all silicon
