This is a good product but when you add all of the extensions together it's very difficult to manage. You're going to need to be really strong and really good to hold all of these extensions when they're connected up vertical as you're trimming. Nearly impossible to do it safely, because it will get away from you easily and maybe fall and hit something AND break it like a window or the gutters on the house or a car or a person or a dog. So it's a little dangerous unless you are very strong and highly coordinated.
