Refillable CO2 45g tank

Aliexpress has just thrown these up at me-

They are screw-together cylinders that have a refilling valve and a release- different threads there for fitting.

I haven't seen them until the last 2 weeks (I browse Ali a lot), and I haven't seen any threads on them.
Anyone use them?

If anyone gets this (and Aliexpress is running 'specials' right now), please let me know. I've got 2x air guns this would/could save significant $$ over the long run, but I was just laid off and don't feel the need to test anything right now. Especially with some finicky MCX units that probably need a full rebuild just to work, according to the 'net.

Remember: See Nothing, Say Nothing, Hear Nothing. It can't bite you that way.
