Product review (4 stars): Make sure you get the right connectors.
Just like the other reviewer had pointed out, you are going to need 3/4 in FIP to 1/2 in MIP adapters to make this work with most gas stoves. I bought this to install a new stove to replace a failing 15 year old range. The pressure regulator on the old stove was near the top and on the bottom on the new range. To make matters worse, the gas line connect valve for the range extends in an iron pipe three feet vertically from the floor. The longest hose I could get was a 48" which put an unsafe kink in the hose and wouldn't have allowed me to leak test it due to clearance issues where the stove was installed. 72" was perfect for that application.  I don't know if it was my location, but no big box home improvement store carried the proper connectors I needed, but luckily, I found a local plumbing shop who gave me the 3/4 to 1/2 in connectors at now charge to complete the job.
