Pros
Perhaps one of the quietest air pumps on the market.
Easy to operate and control with one tap of a button.
Setup is easy with no-frustration packaging.
Shipped in a fully cushioned package preventing damage in transit.
Airflow is powerful enough to accommodate a large fish tank.
Comes with accessories needed to set it up quickly.
Two speed settings give you control over the airflow and noise level.
Cons
Very difficult to find in the U.S. It is currently only available through a global supplier.
The pump is not waterproof or submersible. If you accidentally drop it in the water, it’s inoperable.
To prevent the hose from kinking, the unit must be placed at a higher level than the fish tank.
A bit pricey.

Concluding Comments
Overall, this pump is worth trying because of the noise reduction technology and low decibel rating.
Although the price is above average, your extra dollar spent on this product may be well worth it for the absence of the noise a regular air pump makes.
