SP Bel-Art Frigimat Junior Dry Ice Maker – Compact U.S. Model for Reliable Flake & Snow Ice Production with Durable Brass Nozzle, Easy Setup, and Compatibility with Liquid CO2 Cylinders - Ice Machine Made in USA

I don't agree that this is more expensive than buying dry ice in a store, not by a long shot. It also does exactly what it supposed to: attaches on to any standard CO2 cylinder and when the cylinder valve is opened, produces a ton of dry ice flakes almost instantly. Think of it like a snow-maker attachment except it's dry ice snow. One review mentioned watching tutorials and still being "unsuccessful". I don't know how anyone would even need a YouTube tutorial on how to use this, what is not obvious about it? Screw on to the CO2 tank and turn the nozzle just enough to open it and poof like a fire extinguisher, it fills the bag with dry ice snow. EXCELLENT for kief-making.

I watched at least two dozen videos and still could not have been more unsuccessful.

The convenience is the only thing this thing gives you since it is actually more expensive to use this then to buy the ice already made. And since I live in a fairly large city where every Meijer and Kroger and several other places sell it, I have to decide if this is the way I am going to go.
