Liss Pure Nitrogen Cartridges for Nitro Cold Brew Coffee - N2 Cartridge 10-Pack – For Use with Nitro Cold Brew Coffee Dispenser - Nitro Chargers for NCB Coffee, Cocktails, Tea - 2 gram Cartridges

First, there's only 10 cartridges and the price is way too high. I used three cartridges and all three were duds! No returns because it's "flammable." Well, they delivered it that way, right. Doesn't make sense. The least they can do is provide a good product (OR) a drop off option at Wholefoods like they have for most items. They can be disposed of properly there since you're using your time and gas to return product less cost to them. Taking money for a bad product is unacceptable.

I bought these instead of N20 (whipped cream chargers) to get my nitro to be foamy without added sweetness. It isn't producing the cascading nitro feel I was expecting. In looking at this, it only has 2g of N2, less than most N20 cartridges that are 5g. It will take more cartridges to get the same effect which seems wasteful to me. If you have a small nitro dispenser this will be no problem.
