Review on Zoo Med MagClip Magnetic Suction by Janet Baker

While I like the product design with a wide range of clamp sizes the downside is that they are not very strong and durable. For example, the threaded rod of a plastic clamp can be easily removed. The magnets used are not strong enough to hold a weight in a larger tank due to the thickness of the glass used. I have a 55 gallon tank and a 45 gallon front tank and both have glass that is too thick for the magnet to hold a 28" spray bar with two MagClips. Perhaps modifying it with stronger magnets will provide a solution for those of us with tanks larger than 20 gallons. However, for air ducts and possibly intake pipes, this should suffice.
