CO2 Cylinder Tank W21.8 CGA320 Adapter Converter for Aquarium Fish Tank CO2 tank W21.8 or CGA320 adapter converter(#2)

I bought this with the intention of fitting my co2 regulator on a paintball canister. This is its intended purpose according to its description as of 10/25/2022. What I discovered when I received the item is that the adapter has nothing to depress the pin valve on the canister (it's just a hole in the middle). Gas cannot exit the canister unless the pin valve is depressed. Now I am depressed. Build quality looks fine, but I am rating one star for the inaccurate description.

Four stars for a poor product description, "converts" means different things to different people.Item #1 is female cga320 and male 21.8-14. Presumably #2 is the opposite.

#2 is a CGA320 male thread to W21.8 Female thread adapter.#1 is a CGA320 female thread to W21.8 Male thread adapter
