This tools is genius. The two halves are magnetically connected on either side of the glass or acrylic. The outside half has a glass/acrylic-safe felt layer with rounded smooth edges that are easy on the hand and the inside half has a textured glass/acrylic-safe cleaning surface. The inside one floats should the two halves become separated for easy retrieval and reconnection. Gone are the days of wet hands and carpet from cleaning your aquarium glass or acrylic.
If you're an aquarium owner reading this and you don't yet have one of these... get one. Today. Even if someone else snags this one at the cheaper price, go get one. Even if it's at retail price. In my decades of aquarium ownership, this has been one of my all time favorite tools. I used to waste so much time cleaning the glass/acrylic of algae growth before finally investing in one of these. With this, during water changes, I could quickly swipe across all glass/acrylic surfaces from outside the tank while the water drained.
Takes only a couple of minutes and the glass/acrylic is perfectly clear and clean. No more wet hands and sloshing water everything and stressing the fish out with annoying cleaning wands that never seemed to quite reach the right spots. Especially with larger aquariums. Even if you have a smaller tank, the time and effort this tool saves you makes it well worth the investment. You'll wonder how you ever cleaned your tank w/o one before. When not in use, I just kept it in the back top corner of the side panel and it was pretty much out-of-site.
No issues. Works as good as the day it was new. Retail price on these is $40 plus tax/shipping (see image) but you can get it today to avoid waiting for shipping and save a few bucks over retail. Price is firm and not interested in any offers or trades so please don't ask.

Note: Mag-Float says this is safe for acrylic but I've only tested it first-hand on a glass aquarium with great success. Since acrylic is softer than glass, I'd suggest testing in a small area to confirm but I tend to be more careful than the average person.
