Very well presented valve, gives confidence in its build.
Needed a valve but not in plastic, this valve used in a CO2 aquarium set up. Works just fine.

Useless product
Both valves did not work. Judging by the high number of negative reviews from people with a similar experience, there is a major problem with the construction. Seems like you have around a 50:50 chance of them working.
