Product review (3 stars): A decent value IF you NEED a saddle valve...but you should never use a saddle valve for any plumbing project.
I was in a hurry and purchased this kit for another project.  I knew I wouldn't be using the saddle valve.  Later I realized the tubing can be purchased for just a couple bucks (literally) at the local home improvement store.  There are many other, higher quality, valves that should be used in place of a saddle valve.  Quality of tube and valve is good.
