Anybody using the new Silent Giant air pump?

I stumbled on the new-ish Silent Giant air pump made by Hydra Aquatics today. Looks to be pretty quiet for the size but there doesn't seem to be much info on it other than from the seller. Anybody using this one by chance?

It's said to be about 30dB at it's lowest setting which is pretty great.
