Rated 1 out of 5 by Jeb081998 Not a good filter
First time using this everything started up fine & worked fine. After about a day or two, water started overflowing the filter cartridge spilling incoming aquarium water back into the aquarium without going through the filter process. I ended up changing the cartridge to a new one, everything started working fine again until the same overflow process occurred. At this point I ended up upgrading to a bigger tank with a better filter. I wouldn't recommend buying this filter.

There is no suction cups. The product was NOT as advertised. It was loud, buzzy, and could not be used. Awful.

Bought this filter for an emergency hospital tank for a shrimp in a 5.5 gallon tank.
At first, it worked great and my only complaint was how strong it was.
Now, even after cleaning the cartridge (doesn't even have carbon inside. Took it out for medicine) the water overflows all over the top of the filter. Leaked water all over my living room floor.

After two months of use, both of my whisper filters don't work like they should. I clean them regularly and change out the filter as directed but there is little to no water flow out of them right after I clean them or after about a week.
