Top shelf co2 cylinder

I have 3 cylinders I rotate between fills. Two of which are GLA cylinders and the other a Catalina brand. The GLA cylinder is different in that it not only arrives as if came direct from factory its so new, but the hydrotest dates are super fresh. GLA cylinders are made specifically for GLA. They do not work with any middle man on cylinders and I think this is what sets them apart. They actually keep on record all cylinder stats from the day they were born. Thats what the sticker means on the very top of the cylinder when you receive yours. You will know exactly what Im talking about when you see one at home.
