Dave, I agree, mine is a year old and so far 37 batches of Wine have cycled through it to rack, degass, filter and bottle, and I've used it on over 42 batches of beer to date, that's 48 bottles per batch, over 2000 bottles filled, give or take a few, not to mention racking the beer with the AIO.
Just thinking about doing this without the AIO makes me want to buy a spare to have as a stand by, just in case, a back up unit.
Steve and the AIO are responsible for the increase in production around here...lol...that's my story and I'm sticking to it!
