I've been using the cheap suction cup clips in my aquarium for quite a while. However, they only last about six months and then need to be replaced. On top of that you have to stick half your arm into the aquarium to stick it at the level my fish like it. I've had this one now for almost two months and I love it so far. The magnet works great! It is powerful enough that I don't even have to hold it against the glass to move it around. I love that it floats to the surface when released. I'm hoping it lasts a lot longer than the suction cup versions.
