Review on 2-in-1 KEDSUM Magnetic Algae Scraper for Aquarium Tanks - Floating Fish Tank Glass Cleaner & Scrubber Brush with 2 Blades [Non-Slip, Scratch-Free, Magnetizing] by Debbie Ziliak

I've only used this twice but oh my god I'm happy with it. First off, I originally went to the Petxxxx store and bought something off the shelf and it was so awful. I've looked at all types of products on Revain because there are so many options. I don't know how I came up with this, but I'm glad I did. I assumed that somehow he would not keep his promise, but in fact he did exactly what he was supposed to do. Yes, the magnet is strong and sucks really well. Nevertheless, I was able to maneuver well. My 9 year old had a great time with it and was able to make it himself. There were two blades. One is metal and the other is just plastic. I used the plastic at first because I was concerned about the metal on the glass and the plastic works great so I'll just stick with it. So yes, big difference in the tank and it worked very well. all around for me
