Work good

Very good. Easy to use

The valves had some bur I had to clean up with a file. Not sure it was needed but I did it anyway so the fit on the pipe was snug. So far no problems but it works. Just remember the connect does not have a valve. The Allen wrench is used to seal off the connection. When removing hose, just remember to close valve with Allen wrench or you will release all the refrigerant

Actually worked, was surprised but there was no leaks and easy to install

Worked as advertised. Tried to save an lg refrigerator, ended up calling a local scrap metal guy (Methew) to haul it off.

Helped keep my refrigerator going for another year.

As expected. Worked like a charm. Would buy again!

Not a terrible little device for the price, but it doesn't have a needle valve in it it just has the piercing valve and an o-ring on the cap.
