Bests & Worsts Reviews from Amazon

I replaced my old refill valve with this one and am very happy with it. The quick attachment design eliminates the need for a wrench and makes filling 1lb. tanks a quick process. I can attest,that contrary to what others have stated, that it is indeed very possible to overfill your 1lb. tanks. I strongly encourage anyone to buy an inexpensive 0z./gram scale, which can be purchased here on Amazon. I weigh my empty tank, and then add no more than 16.4 ounces. Many times you will end up with a tank that is 1/2, 2/3, or a little less than full, and this is great. I filled eight superchilled empties and overfilled three by 1-3 oz. on a hot day (about perfect conditions for doing this). I decided to bleed off a small amount to be safe. I have read that overfilling by small amounts is ok, but have also come across many accounts of bulging tanks that were overfilled, so I don't chance it. Do not under any circumstances do this inside and I would not even do in a garage with the door open. Do it outside , period. There are several YouTube videos that will walk anyone through the process and if anyone hasn't done this before I think it's good idea to check them out.
