Tetra® Whisper EX20 Filter System
My filter worked good for 1 year and 2 months, then died completely. I have used others for years. i am not satisfied.

Works well, but louder than expected
I bought the Whisper EX 70 for my 55 gallon freshwater tank. It was very easy to set up, though I'm surprised that the impeller is in the tube, and a little dismayed that the cord gets so close to the water - the engineering doesn't seem well thought out. It's also quite a bit louder, mechanically, than my old MarineLand filter. The indicator strips are a farce - I've had the filter in place for about 2 weeks and it's already telling me to change the cartridge, which is unreasonable considering the cost of the odd-shaped replacement cartridges. But, the water in the tank is very clear. I like the special insert for facilitating healthy bacterial growth. The large filter and long tube ensure that the water circulates well through my tank. All in all, I give this a "good" rating, but it's not a perfect product.

This product had cheap features
The part of the filtration system that sticks into the tank water that sucks the contents into the filter keeps falling off after 6 months of purchase of the product. I now have to keep reaching into the tank at least 2x a day to place the piece back onto the base of the filter.
