Rated 5 out of 5 by Eric5150 Great air pump and it is quieter than all others
I've been using a Whisper 40 air pump as well as a Whisper 100 for the past year. The Whisper 100 has been powering my LED bubble wand, bubble volcano, and animated treasure chest with more air to add more things as needed (I put some entertainment in my 2 year old's show tank). I have some old pumps that I used to use in the 1990s and both are very quiet compared to all of those pumps. You need to make sure to put them on a level and proper surface for maximum quietness.

Rated 4 out of 5 by Bush66 Great Service
I purchased a ex40 pump and it was great, has lots of power, and is quieter than a cheaper one I had. But it did break after a month, suspect some defect. I recieved fantastic service from Laura in consumer relations. She stood behind the product and got me a new unit within a week. Very impressed with the service from Tetra. Will definately purchase more products from Tetra

Rated 2 out of 5 by cregtim23 work well for a while
Worked great for the first 8-9 months but then the rubber cups cracked and no longer works. Repair parts cost over half as much as pump and by the time you pay shipping it ends up costing you more.

Rated 1 out of 5 by Berrythebetta Was wonderful for a month
This airpump worked great and it was very quite. However after about a month it became incredibly noisey and it did not pump air affectivly. I wish Tetra would make better quality products.
