I have one but haven't used it for a while!
It was a present but only because I suggested it!
I must get it out again and give it another go.
However it has blown over in the wind previously so don't park it broadside!
Mine got exchanged for a new one because the stitching on the handle was faulty.
It might not fit in the boot of the new car whereas the guns in a slip just fit diagonally in the boot.
There are certainly some shoots where they would not be room around a stand for everyone's Hamilton let alone the shooter's equivalent of a golf trolley.
