Here's the reply from my friend...
"I checked out the post and will email the guy since I'm not sure about a login on the site. It is a nice system. I like that you just stick it in a carboy (better bottle, it is thicker than a standard glass carboy). It takes some time to cool, like 1 degree / hr and longer as is gets cooler but it will go down to 35 below room temp. The "sleeping bag" it comes with is key. Once temp is reached it is very stable. It does make some fan noise that is louder than you would think necessary when it is actively cooling.
I know it was designed to be easily upgraded in the future for heating and wifi."
