As the other reviews statehis is the best magnetic scraper I have ever used. I've used hammerheads, magfloats, and Kent. This scraper beats them all. My only complaint is that the scraper head does not extent the full length of the scraper. Example: the scraper head is approximately 3 inches but the metallic scraper is only 2.25 inch leaving unusable space on the scraper head. Annoying but still worth the cost.

This is the best scraper I have ever used. I was a little worried about spending $45 on a scraper but it's well worth the price. It made a normally arduous task very easy. I used it with the magnet and without to get at the back of my tank and it worked well both ways. Best scraper ever!

This is an excellent product! The magnet is extremely powerful and allows the scraper to effortlessly remove material from the glass. Interchangeable scrapers, including metal, are included to remove anything from your glass. The scraper will not trap sand so there is no worry about scratching the inside of the aquarium. The blade size allows it to easily follow the curves of my bow-front tank. The only problem, and it is very small, is that the scraper does not float. You may need to retrieve the scraper from your tank if you pull the external magnet off while scraping but you will not do this accidentally because the magnet is too strong. Overall, this is the best scraper that you can buy!
