Rated 5 out of 5 by from Another Win! I had the old gas trimmer 4 stroke that could take attachments. So naturally over the years I collected many attachments. When I decided to make the switch to 40v I went with all the tools so I would never have to fight gas powered tools in the spring again! No more winterizing, spring cleaning, oil changes, and pulling cords again! All my collection of attachments work flawless with this tool. I can run my edger on the low setting and it never struggles. Cutting branches with the pole saw works as good as any gas powered I have ever owned, 2 or 4 stroke, and I have owned several that always failed eventually. 1 battery with plenty of power to spare no matter what job im using it for. If your thinking of making the switch you won't regret it, I definitely don't!

Rated 4 out of 5 by from Nice unit with many optional tools Great performance and trimming power. The only thing is there is a loud squeak noise when you let off the trigger. This is the second one I've had and they both did the same thing.
