After going through so many commercial brand air pump that would die off after a few months of use, I decided to go for a more specialized product; I couldn't be more satisfied!

This pump EASILY provides a large amount of air to 9 poret filters and 4 air stones, and even then I have to leak a large amount of air off, which comes of use when I want to add air to bath or acclimatization bags.

For the amount of air provided, the sound and vibration produced is insignificant - to be fair, I don't even know it's there behind the dehumidifier.

The build is solid, and I know this will last for much longer than any fluval, eheim or tetra product. The price is 100% worth it, this can easily replace multiple "high output" pumps of the aforementioned brands, for an extremely good price considering how many pumps it can replace.

Highly recommend!
