I love that I can use this magnet and get around the my tank. I have the UNS 5N and I am able to get all sides of the tank without taking the magnet out. It's a nice size and does not ruin the tanks modern style. The only reason it gets a 4 star is the edge happened to have a little crack and the middle portion with the logo bubbles out. I've had it for a year now. Overall a good magnet in my experience.
