I bought the stainless version for durability and safety. This model was great! It is easy to use and clean. I've used it for both whipped cream and nitro coffee and it hasn't disappointed. There is no need for any special coffee nozzle. I found it easiest to make coffee separately and leave it in a pitcher to cool in the fridge. If you use granulated sugar ir sweetener you shoukd mix it outside the dispenser so it is thoroughly dissolved and won't clog the dispenser. I use nitrous cartridges for nitro bre coffee and it works absolutely fine. To make whipped cream, you must definitely mix all you ingredients outside the dispenser. It comes with recipes but you can certainly experiment your own recipes. Tips:
Make sure ingredients are cold and make sure the dispenser is cool before filling. This will ensure good results.
If the threads on anything seem tight, a little veg oil on threads can help.
Handtight only on everything. No wrenches.
For whipped cream use heavy cream.
One nitrous cartidge per pint is sufficient for coffee or whipped cream.
For nitro coffee, open the nozzle slowly.
For whipped cream, you can open the nozzle a little wider.
Keep the dispenser upside down when dispensing.
After sitting in the fridge, shake the dispenser a few times before using to remix the gas with the product.
You can freeze whipped cream as soon as you make it. Just discharge into a bowl or other container and cover. Makes a great frozen treat or can be used if allowed to thaw for a fewinutes.

HAVE FUN!

It's a very solid item. It's well made.

I've had it for over a year now and it's still works perfectly

i loved this device. But I haven't been able to use it since the divorce because I only seem to have the container and the lid. I no longer seem to have the different parts for the lid. I've lost the spouts and the charging tube. can I just get replacement parts instead of a whole other complete kit?

The media could not be loaded. Nitro cold brew coffee is almost too easy with this tool. You want smooth, creamy, frothy, sweeter (as in really is black, no actual sweetener needed, but via the placebo effect in texture, it tastes sweeter) coffee? First take your favorite cold brew, preferably made yourself by grinding your own beans then doing at least 12 hours in filtered water (all those things make a huge diff). Just pour up into this tank, I fill it all the way to the top and it works fine, no explosions, about 20oz, then use your n20 tanks, you can do isi brand for example, as long as they're 8g size n20s, and dispense for the most luxurious black coffee you can have. It tastes even better than Starbucks nitro imho, because you can use your own bean preferences. I use a medium Chiapas bean with dark chocolate, creamy and rich tasting notes. So in the end my black coffee is essentially like a cold-hot chocolate (like the kind at Christmas) even though it's not sweetened, flavored or with any additives other than nitrogen. If you do the math, you're looking at 50cents per cup of brew, including the price of beans, if you get your n20 tanks (charger) on amazon, like the 50 pack for 30$. Then each n20 tank will do 20oz(my overfilled canister ;) ), so really 2.5 cups per n20 tanks used, that's about 50cents per cup bc my beans are 11$/lb and I do 4 oz grinds per gallon(128oz) for cold brew. How much for a grande nitro at Starbucks? 5$?! So if you drink this everyday as I do, 15$ a month vs 180$/month at Starbucks, ouch, not sustainable!! But this method is! And this is premium, best of the best, hipster stuff. You can't get a better, imho cup of joe than this. And it's important to do a 1L (this) size vs a 8oz mini(1/2 pint), bc each 8g n20 cartridge/tank/charger will do 20oz with a bit leftover, but if you do the 8oz one, you waste tons of n20 and money! I started with the 1/2pint whipper and upgraded. Honestly I could probably do a 1.5L whipped cream canister and it'll for sure use the whole n20 with no leftover wasted gas. speaking from experience and tons of experiments guys, this is a winner here! You can do xantham gum powder(1/2g) with your brew and blend it like crazy, which works well too, but n20 infusion tastes better, but you'll want the best. xan is close too, and far cheaper! Also I have the uKeg nitro growler that specially makes nearly 2 liters (64oz) of nitro cold brew that includes a tap (which supposedly helps make it frothier and cascade more thus tastier) but this whipper is far superior at cascading and making it creamier thus tastes best.
Update 6-11-20: eventually the trigger handle bent after overfilling coffee tons of times which means it was hard to squeeze bc of the force required after n20 discharged inside, so I"˜m using a diff lid/nozzle from another model but the eurkitchen canister is the best bc it's more insulated even tho it's just the aluminum one, but compared to the other dispenser, it's much heavier and thus maintains colder temps out of fridge longer. Now that I see there's a stainless model available I've got to get that to withstand my overfilling! Which makes the creamiest nitro. Fill to top, dispense n2O charger without shaking which somehow creates this cascading effect best bc the bubbles are tinier/more fine, so still the best nitro coffee you can DIY, don't waste money on a growler!

These work exactly as advertised. I have used about 12 of them so far and they have been great. They impart no weird flavors and every one I have used has worked perfectly. I even sent some to a friend and he reports they have been great as well. I highly recommend these whipped cream chargers!!
