Question: So if I am only user of this would I be better off to get the 1/2 pint version? Do you lose NO2 charge when refilling with cream mix?
Document: Worked fine as stated. I did however notice that the cream seemed to come out whipped better with the pull tab on the seal placed in line with the charge port on the cream Whipper head. To those who wrote negative reviews that the creamer seemed to not take a charge and the cream gurgled out, I would say, there are some tutorial videos on Youtube that are helpful. The instructions of after charging shake 3 to 4 times is just that, 3 or 4 times.
It... makes whipped cream. It's a cream whipper. You'll end up going nuts spraying whipped cream directly into your mouth for a while. It takes a minute (or a pint of cream or two) to get over that.
I love, love, love this iSi Gourmet Whip Plus, 1-Pint, Brushed Stainless Steel, Cream Whipper! I am continually finding new uses for it, it is easy to clean, transports well (Thanksgiving Dinner)  and VERY well made.
This gadget does the job both for NO2 (cream) and CO2 (soda), even though it is not designed for the latter.You should expect to waste around five cream charges before you understand how it works. Once you get the hang of using the machine it works very well. With NO2 you only fill to the 0.5 liter mark. (And for a good result you need to fill to the 0.5 liter mark.
I was looking for a professional siphon that could handle sweet cream as well as savory whips with ease, and found it in this iSi Whip Plus.Easy to use, and incredible with cream and pur&eacute;ed herbs to top a soup.And, of course, whipped cream in any flavor you think of.I chose the pint, better to err with too much than too little, since both sizes will spend a full cartridge.
this thing is awesome!!! the strawberries are in season and i love strawberry shortcake with whipped cream!!! this little cream whipper produces a full pint of fluffywhipped cream just like the kind in the canister at the grocery store.only better and way more of it!!! i like this whipper because you can make the whipped cream without sugar or flavoring, which really lets the flavor of the strawberries shinethrough!! !great product!! !
I got it for my girlfriend who's addicted to whip cream. I had one as a kid growing up and figured it would be perfect for her. I haven't tried anything other than whip cream just yet, but fresh whip is soo much better than Easy-whip.
This whipper replaces my Kayser dispenser, which served me well for about 15 years, but the plastic and rubber started to disintegrate. What a difference in quality and design!!! Unlike the Kayser, you can remove the tip without discharging the unit, so you don't end up with cheesy cream in the tube, nor inadvertently spray whipped cream inside the fridge door. Also, I love that this is dishwasher safe. I would say that this is the BMW of whippers. How could they make it better?
Had and earlier version of this that just whipped cream. This product does lots more! Everything I could ever have asked for. Love it.
I've only used this a few times and at first it was perfect, but now, when I load a canister it releases half the gas while I'm still screwing the holder on, even if I try screwing it on as fast as possible. Disappointed and feel I need to buy a new one, yet this was expensive. I thought it would be better quality or at least last a while.
Answer: Depends what you're using it for.  I have the pint size and it didn't produce as much volume as the mixer but it is a completely different texture-yum! But I only used one NO2 cartridge ( didn't know I was supposed to use 2 for a pint based upon the other comments) and it failed to cover a 9 x 11 desert last Thanksgiving when I took it out of town with me so the cream wouldn't melt.  It covered about 3/4 of the dish as I recall.  Had to spread the cream...so much for trying to be decorative. Of course it's possible it would have gone further with 2 cartridges and more gas.   I've also used the unit to make whipped cream at home over a two week period.  Kept it on it's side as instructed.  Just shake it up before serving and it worked fine.  I did add a second cartridge half way through and it was even better.  ISI makes a great quality product and everyone who's seen it thinks it's cool, serve's the best whipped cream and they're so envious that they say they've got to get one.  Personally I'd get the pint size unit for the option to make more cream when needed.  But take a moment and think about what size whipped cream do you normally buy at the store...1/2 pint or pint?  This should pretty much tell you what would work best...unless you're a Redi-whip user.    Hope this helps.
