Query: Does not work

So far I have used this tool to hook up 2 valves and no matter how many times i use this tool they both slightly leak. A piece of the 1/2" part of the tool chipped off the first day i had it. And the most ANNOYING part of all is no matter what you do when you take your vice grips off the tool will separate and fall off the floor, which is not so fun when you are working on a ladder. I bought this tool to try and save money but ended up just wasting it. Save yourself the trouble THIS TOOL DOES NOT WORK!
