I have tried them all, magna scraper, mag float, mag float scrape and the smaller version of flipper. This is by far the best product. It scrapes coralline algae without effort. It is large 6.5x3, and recommend it on large tanks. Worth the money.

I've been in this hobby for more than a decade and this product is by far one of the best purchases I have ever made. Buy it now! You will be happy you did.

Let me just say that this thing works perfectly. I'm usually very worried about scratching the glass with sand with other scrappers, but this one eliminates that fear. Not only that, but I only need to do 2-3 scraps to eliminate that pesky coraline algae. Otherwise it takes 1 pass to remove all other kinds of algae and makes for keep the glass clean a breeze.

Made easy work of the coralline build up on my glass. Works as well as I could have expected.

Throw out all other glass cleaning magnets and long handled scrapers. Or save money and buy this one from the get go if starting out in the hobby. I wish this product was available 13 years ago when I first set up my tank. I would not have the handful of scratches from my old cleaning practices. I can not comment on the effectiveness on acrylic tanks as mine is glass.

I have a saltwater bow front tank. And as all of you bow front users know, getting a scraper of any sort for this kind of aquarium is impossivle, nothing is shaped for it, except for this thing. The scraper works like magic on my bow front. usually I had to detach a scraper from the long arms of other scrapers and put my hand in the tank. But that's not needed anymore. This thing is a must have, I know the price is steep but you won't regret it

This is AMAZING! After using run of the mill magnetic cleaners and wand style steel bladed scrapers on my glass tank, I had gotten to the point where I was not looking forward to glass duty. It's messy and only marginally effective. I received this in the morning, placed it in the tank, and 5 minutes later, all my glass was clean. DONE. It WORKS. This is only useful for flat pane tanks. I don't think this would work well at all with rounded panels of any kind. It does come with both a stainless steel and plastic scraper attachment so you can scrape your plastic walls as well. I highly recommend you pull this out of your tank after use. It will last much longer. Whatever you do, don't leave the the side with the blade pressed up against the wall. I can imagine this would ruin the precise angle and pressure being applied over time.

The flipper scrapper is fantastic! The scraper cuts through coralline algae with ease. The flipping function is nice, because it allows you to switch between a scraper and a scrubber without even getting your hands wet. When using the scrapping side the flipper distributes its force along the blade and two small rubber balls. This greatly reduces the chances of scratching do to a piece of sand getting stuck between the flipper and your glass. It also puts more force on the blade which allows it to cut through algae more easily. Another great feature of the flipper is how thin it is. Its thinness allows me to clean areas that used to be unreachable due to limited space between the rock and the glass. Overall I really like the flipper. I would recommend it to anyone with an aquarium. It is definitely worth the price
