Product review (5 stars): Great for refilling fridge gas.
Use this on my refrigerator to refill the gas. Was not sure exactly how it worked so I looked up the process on youtube. Long story short I had my fridge topped off and as cold as the first night we brought it home new. This saved me a couple hundred dollars over having a service person come out and deal with it for me, and now I can refill it my self in the future!
