EXTREMELY easy to use! Requires very little effort to relieve pressure from a female QD. Almost like a light tap instead of the way it use to be which was slamming a stair/ hydroforce spayer multiple times as hard as possible into the ground. We don’t use it often (4 times in 6 months), but it’s small and works very well. Every cleaner should have one of these on their utility belt for peace of mind.
