OK, we've been running this one for about a month now and I got a solid workout over that time. It's currently running 8 kegs and a couple in reserve.
I must say, while I found the running noise a little excessive in a quiet atmosphere, you don't notice it after a few nights sitting close by. Certainly in an enclosed bar area or in a commercial setting, it'd be fine. The menu for the controller is simple for changing the set point, but as you get into the deeper settings, it'd be easy to get lost in the woods. Mine is set for 4 degrees, figuring beers will warm up a few degrees fast enough after pouring.
The provided font fans do a decent job of cooling the beer to a point where it's still at the nominated temp at the glass.
The light inside is a godsend.
We set up hoses running to an adjacent drain to cater for beer spills and excess condensation, though they tend to need a flush after a big session with inexperienced people pulling taps etc. all good.
The fridge pulls down room temp kegs fairly quickly and cycle times aren't any longer with one or two fresh kegs going in.
The top comes wrapped in a protective plastic coat which is a pain in the arse to remove and clean up afterwards. Be prepared for some hard yakka.
Overall, pretty happy with the unit, but it's probably overkill for the average guy running a few kegs. But for catering functions after a club competition where there's 40+ people pulling beers it's excellent.
Edit note. It might be good but it doesn't come with gravity defying ability....it's an added extra thanks to AHB's arse about photo uploading protocols.
