Eh, you can give a grigri to a 6 year old kid and they won't fuck up, will not drop their climber and will not get their hands stuck in belay during fall. You have to be an active idiot to screw up grigri.
Also it makes it easier to set routes without having to make your own autoblocker or abseiling.
On personal note, we are currently using pic related in club and it is a good cheap alternative to grigri.
