Excellent, quiet but powerful pump. By Joseph on 3/8/12

Vastly superior in every way to the now cheaply made MaxiJet brand. Get the Cobalt, you won't be sorry. I use one for my mixing bucket, another to run my reactor and UV and keep another in reserve. You can't have enough of these - and they come with everything you need to convert it for a variety of uses.
