I'll update this review when I get to use the item, but the recommended combo on the page was with the wrong cartridges, and there were several Q&A that said this takes unthreaded carts. Maybe the design has changed over time but as of August 2022 you need unthreaded 16g CO2 cartridges. Simply placed the plastic grommet into the top of the pipe (see pic) and pressed the trigger.

I never have projects that finish without unexpected incidents occurring, but this one worked and finished in about 5 minutes! That aside, took me a couple tries to realize I wasn't getting a good seal, but once I did the A/C condensate drain line was utterly bone dry, with a small ugly pile of white algae on the ground next to the exhaust. Air did flow into inlet, but enough pressure went straight down to unclog it. Probably going to make this a regular maintenance thing, once in summer, once in winter (Orlando, FL).
Got the Co2 cartridges at a local bike shop, so with same day delivery (Prime, yippie! Here's a picture - 12 gram is too small for the container and as you can see, its clearly threaded. Made no modifications to the drain line, like several friends suggested.
