Product review (3 stars): Wrong and missing parts
I am giving this 3 stars because it does not come with all the parts needed to install to your fridge. The piercing saddle has instructions along with the filter but if you are not familiar with the parts used to instal get help. Both the saddle and filter work fine with no leaks. You will need to buy teflon tape, 1/4 inch compression nut "it comes with a copper ferrule you don't need". Buy two 1/4 inch compression sleeve and insert for plastic tubing. Now you have all the parts for Polyethylene Tubing. When you are done you will have three copper compression ferrules left. They are small rings for Copper Tubing, you don't need them. Now mine is installed and i'm harvesting ice.
