I've had the B95 BeerTender for about 3 months/6 kegs. I can't personally verify that the keg stays fresh for 30 days because we've yet to take more than 2 weeks to empty a keg. But all indications say that it would remain fresh. It's easy to set up, easy and fun to use, and keeps the kegs at a great temperature. You need to purchase the disposable tap tubes (they are not reusable), but they are reasonably priced, so I stock up on them. You wouldn't want to reuse them, anyway, as that could be unsafe. One of the biggest hassles with big kegerators is the need to sterilize the tubes and pipes, and this negates that problem. Aside from having to drink Heineken exclusively, due to the lack of other compatible kegs available (which will hopefully change!), the only technical negative I have experienced (which has kept me from rating this 5 stars) is the fact that the volume indicator on my unit does not operate. This appears to be a design flaw, and it's up to you whether the possibility of your unit having this flaw prohibits you from spending the money on this product. Only once has the volume indicator on my unit read anything below 4 bars (full) as a keg was drained--even when empty. Even after following the "troubleshooting" instructions in the manual, it did not operate correctly. The single time it seemed to be working, it went from 4 bars down to 3, and then down to 0 almost immediately, as the keg was emptied with a final 10 oz. glass. It's annoying to not have this feature work correctly. Other than this, I have no complaints, and truthfully, I probably would have bought the item even if it didn't have a volume indicator at all. Nevertheless, it is helpful to have that feature working correctly when you use it intermittently and lose track of how much might be left in the keg. We had an instance where we thought we had enough left and offered a cold glass to a visitor, only to have it spit foam and air at him because the keg was empty. I contacted Krups about this and was told to ship it to a service center--too much of a hassle! ElectroBest.com is an independent Krups dealer.
