Mypressi Twist Stainless Steel Replacement N2O Chargers, Pack of 24

I own a mypressi twist, and have bought a couple of these boxes now. I previously bought the ISO n20 cream chargers, but found them inconsistent with the My pressi Twist. Sometimes, I would get a couple of pulls out of the cart, sometimes 4. This was a problem in that you don't want to get half way through a shot and run out of pressure.The mypressi twist stainless cartridges are very consistent. I know that if I am getting 30 second pulls for a shot, I get 3 pulls. If I am pulling 20 second pulls, I can get 4 and a little more. Every cartridge shows the same.In two full boxes of 24, I had one cartridge that only lasted two pulls.In all of my research in portable espresso, I have found that to get the best espresso shot within limitations, you want as many variables to stay consistent as possible. These cartridges are the answer for me.

I purchased this product to take to my work. Since it uses pre-heated water, it doesn't need a heating element, and thus meetings my building code at work.I've used this thing a couple of times in the month I had it at work. While it's nice to have something I can take to work, it takes about 10 minutes soup-to-nuts to make a cupful of espresso shots. Because of the duration, I make more than I need and save half until a few hours later.Pros:- great espresso- nice crema- meets my building code- easy enough to cleanCons:- takes some time to use- quite a few parts; so far haven't misplaced any ...I give this one-of-a-kind product 4 out of 5 stars, and would recommend it to those with a need similar to mine. For reference, if my office didn't have the restriction on machines with heating elements inside, I would have a small automatic/semi-automatic machine on my desk (or, perhaps a Nespresso). I wouldn't be able to stow that in a drawer, but it'd be much quicker to use, and I'd probably use it once daily.Jon
