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.

I purchased this pump yesterday and its already making a racket. I took it apart to see if there was anything noticeably wrong with it, but everything seemed to look fine. I don't know if I just got a bad product or what, since there are reviews our there that state this thing lives up to its name, or at least it did until it fell apart, but that has not been my experience at all.

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 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.
