Review on Efficient Magnetic Aquarium Glass Cleaner & Brush: Saim Fish Tank Cleaning Tool by Dawn Jackson

I've been using this for a few months now and it's a great cleaner. I've used it on 10 gallon tanks up to 125 gallon in length and it works great on all of them. It has a very strong magnet and is easy to use. Comes with plastic and metal scraper and both work perfectly. However, be careful when using it on thin glass when you first put it on the glass as it may break if you are not careful. I love it so much I bought my second one and plan on getting it for all my tanks.
