Had my hornit horn for near 10 years now and wanted to upgrade to the V3 mount.
Bought one, but after only a few months it cracked and the thread insert for the bolt became loose, so was unable to even unscrew it off.
The sizings for the rubber inserts are all basically the same, had to source extra rubber strips to make sure it fit properly.
Plastic around the bolt is very thin so be mindful when tightening!
But otherwise very convenient for mounting and dismounting the horn when on the go, and with extra rubber straps it does seem to hold in place (for now) in the rain
