AC Pro Car Air Conditioner R134A Refrigerant, AC Recharge Kit Includes Gas, Gauge and Hose, 20 Oz, ACP200-6

are the directions clear and easy to follow?

if i need to recharge my ac again can i use the hose on a different brand or will it only work on ac pro?

All the components of my AC system are in working order and I'm just wanting to top my system. Is this product useful for this purpose?

when using this or any other product to add refrigerant, to you risk destroying any part/s of your a/c system? thanks!
