It works just as stated. Only thing you must be careful with is that the magnet catches from the back side of the scrubber also. And if there's any hard build up, and you swipe, you more likely will scratch your glass. That's how i got a 6 inch scratch in my front glass :(
So please be aware of what side it's on before use.
Other than that its the best magnet scrubber ever used.
Great product By Smallreef on 1/14/14

I have always had Mag floats; but with this new very thick acrylic tank, it just wouldn't hold on, let alone clean anything. Ordered the Floating Tiger Shark and I have to say I am very pleased; not only with its hold...these magnets are strong, but the cleaning ability, and the extra pads included. I feel this magnetic cleaner will last me much longer than any product I have previously used.

I've owned a few different types of magnetic cleaners and these are above them all.. what i would recommend is do not go with the plus 1 method with these bad boys.. get what your need in your size criteria.. these magnets are strong!!! a few swipes and its clean.. i could only imagine a stronger one will be very difficult to move.. definitely would recommend..
Beast mode magnet By Collin on 12/15/13

This magnet is industrial strength. After a few pushes across the glass, your arm will get tired---and that's a good thing! Lots of power to clean those stubborn algae spots.
I highly recommend adding the algae scrapper with this magnet. Adding the algae scrapper lets you easily scrape away coraline algae.
This is easily one of the best investments I've made for my tank. The upfront cost may seem like a bit much, but in this hobby, you get what you pay for. Totally worth the purchase.
It also includes an extra felt and scrubber pad.
Tip: Keep the magnets apart when not in use, or else you'll stick the felt onto the cleaning pad.
Best magnet I ever owned By Matt on 12/6/13

I purchased the Piranha Float black Fri/ The magnets are SUPER strong! You really have to put some effort into it in order to get it to slide. It gets the glass clean in only 3-5 passes.
Good product By Shawn on 11/5/13

These glass cleaners work extremely well and will remove calcified algae from your glass with little effort. I find the pads don't wear nearly as long as I'd like but with magnets this strong it's easy to understand why. I find if I use glass polish before cleaning my glass things move much more easily and makes the felt side last long due to reduced friction.
Worth every penny! By Roy on 8/23/13

I purchased the Hammerhead a few months ago and love it. I used a mag float before and with my 1/2 inch glass it would fly off if I went too fast. The hammer has a very strong magnet the will smash your fingers if your not careful with it. I used to worry about scratching my glass but not with this one.
Very good product and worth the high price
AS ADVERTISED. BEST CLEANING MAG ON THE MARKET. By Chicago C4 on 8/21/13

This product proves you get what you pay for. I don't see myself ever buying another brand cleaning magnet again. Bought the Hammerhead, and it's exactly what you expect -- awesome, plain and simple. Definitely more expensive than others, but absolutely worth it.
Powerful! By Chad on 7/23/13

I purchased the Piranha Float when I first set up my saltwater tank. The magnets are SUPER strong! You really have to put some effort into it in order to get it to slide, otherwise the cleaner kind of "skips" along the glass and can splash the water around a bit. It gets the glass clean in only 3-5 passes. Other cleaners could take up to 10-15 passes. It is a little bit beefy and bulky, and can be hard to fit into tight spaces, so I purchased a smaller, weaker magfloat to clean the glass right next to the powerheads.
just too powerful for my 50 gal By Joe on 5/25/13

I pickup the Piranha float, but I just find it a little too large and powerful for my 50 gal tank with 1/4" glass, so I find myself using a smaller mag-float instead.
Strong Magnet! By Dan on 5/22/13

This cleaner has a super strong magnet in it. To the point where I start to put pressure on the stand (30g). It cleans well, but the price needs to come way down. It's a block of wood with some felt and a plastic block with velcro...
