from Works great ! I've used mine for more than 10 years. I dropped the canopy on it the last time, otherwise it would still be working.

from Initial noise, quiet after 24 hours This product effectively keeps the environment at a stable level. It is initially noisy until water has saturated the media, but then it is quiet. This will last 2-3 years under normal circumstances.
