Very satisfied with the purchase. The adapter fits very well with the CGA-320 connection CO2 cylinder. On the other hand, it fills the smaller TR21-4 connection cylinder without any problems. Everything was fine with the item. Responsible and recommended seller.

Fast shipping, it fulfills its function, but the valves seem more decorative than anything else, quite confusing to use, but it's safe and the safety valves seem to work properly.
