Review title: Simple and affective
Product review: This is the first time I have had this type of product so I was not sure how well it would work. The concept is simple and the results are good. The magnet is very strong, almost too strong if you need to move slow around objects. The cleaning face is the hook side of Velcro and does a good job of scrubbing any algae. I had no problem going around corners and the narrow size handles the curve on my bow-front tank just fine. The best thing I could say about this item is I would buy it again.
