I have one and love it, it's great standing there watching the young lad who works for me reel his hose in by hand while I stand there just guiding my hose onto the reel ☺. I may buy him one if he keeps up the good work. It's an extravagance but we'll worth it, if it makes your body last longer in this game then all the better. Safety wise, your stood away from the reel as it winds in as you need to fix the reel into the van, if you want to stick your hand in then it will hurt just like if you stick your hand into a lathe or drill, most people have enough common sense not to do that.
