You probably all already know this, but I'm putting it out there for anyone that doesn't. I have had issues with trimmers. I haven't truly liked any of them. But these..... these are the Rolls Royce of trimmers. I trust to cut anything bigger than fan leaves with them because I don't want to mess them up. They are absolutely perfect. Lightweight, no spring, no hands cramping, and cut like it's nothing. The brand is Chikamasa. I have the B500f model. If you trim at all, you NEED these in your life!
