Product review (1 stars): go piece together your own kit....
I wasn't planning on using the puncture hook up (neither should you) so I can't review that.  The tubing itself seemed to be thinner than other tubing I have found.  Additionally, it arrived with a few "dimples" in the copper and was extremely prone to kinking.  I ended up having to cut the tubing and splice a 10 ft section of (better quality) copper lines I bought at Home Depot to replace a section that was not usable.

Honestly copper is the way to go, but you can get a 20 ft section of copper refrigerant line from home depot and a copper t fitting from home depot and it will be better quality, and more kink resistant tubing that this product.
