A mark to let you know if it is in the on or off mode would be nice. Just remember left is closed and right is open. I use this when I put my tank on my marker, but don't need it when I use my remote. I paid twenty bucks for it at my local pbs.
A good puchase if you don't have an on/off valve on your tank.
