Rated 2 out of 5 by ShaShaGrace Works okay, but limits options
I prefer not to use carbon in my filters because it removes medications (I only add it after a treatment when I wish to do so). I would like to see a non-carbon option (such as the "you-assemble" value packs for the older Whisper filters, which I just left the carbon out of). Right now I'm treating a tank for ich, and I had to rig up a filter out of the wrong-shape filter inserts so I would still have some filtration during treatment. How annoying! However, I gave the product two stars for convenience alone, because that's what's most important to some people.

Rated 4 out of 5 by PurpleHel Frustrating that they don't make the economy packs for this model!
These filters are great, but it's very frustrating that they don't make economy packs for this model. Also, only having pre-made filters available is inconvenient when there's a situation where one needs to run a carbon-less filter.

Rated 4 out of 5 by thompson Over all this is a good product.
I like this filter. Its very quiet, and the flow of water is great. However 15 bucks for 4 filters is a high price.

The filter is great. The price is below average $15.00 dollars for 4 filters? Tetra needs to lower the price way too expensive.
