Performs the exact function described. Works very well.

JUST WHAT I NEEDED

Good

Good filters and a good price, works very well in. my fish tank

excellent!

have used them before and will continue to use them in the future

Excellent for Aquariums

The product is fine, does what its used for. My issue is the packaging. Instead of putting it in a box it was in a cheap paper bag! The box was crushed which crunched the filters and released some of the charcoal. VERY disappointed!!

Great
