Review on Jasonwell Magnetic Aquarium Fish Tank Glass Algae Cleaner - Floating Brush (L Size) by David Hashman

I bought this magnetic tank cleaner a couple of months ago and it's been working very well. I had a lot of hard water stains on the glass that I couldn't remove and now I'm seeing them less and less which is great.One thing I would suggest though is to have some directions/instructions included in the box because it took my boyfriend and I a while to figure out how to attach the blade correctly. Even just some close-up pictures of the blade inserted would help. Other than that, no complaints.
