Morning Andyman
Yes they work good i have a electric one . And they are safe to, they are a little hard to use when you get then fully extended a little heavy and hard to hold you have all that weight extended out.Does not seam like a lot but it is. Sure beats getting the ladder out and moving it all around every time you want to trim a branch. I can only cut about a 4 to 6 inch branch , and remember they are falling on top of you if you stand under them. And you do have to have a electric cord to pull around with a electric one. I like mine .
