SNUNGPHIR Algenmagnete 100490 Floating Magnet Aquarium Cleaner, Large

Excellent product, keeps my aquarium glass nice and clean. Have tried other makes, but find this one the best.

Good strong magnet which allows you to switch from one glass pane to another on the corners. I bought a cheap version which was a mistake as it scratched the glass on the outside due to poor quality materials.

Does the job but for "extra large" they arent that big especially for the price charged

My tank is unfortunately near direct sunlight so this has helped keep on top of Algae build up. Seems to get most of it off with a couple of passes so overall very happy with this.

It works when its not trying to release itself and float about in the tank I have even started using two magnets in an attempt to keep this on the glass "in the water" from one pane to the other every time it floats straight to top and then blasted about in the tank every other mag float i have had you could at least get from the side pane to the front pane without it flying off put less buoyancy in the damn thung

This is not what is pictured, nor is it what is described. The description states the following dimension: 12.5 x 5.51 x 16.99 cm, as you can see from the photo, the dimensions do not relate to the item itself, but to the packaging that the item comes in. I will be returning this item.

Have purchased this item before and found it to be good great glass cleaner

Like it , it has a certain magnetic charm.
