I too have been wondering about this same thing as I have a bunch of compatible batteries already. I was looking at the trimmer with the 135 degrees hedge attachment and the standard hedge trimmer. I don’t like the look of the blades on the hedge trimmer compared to our Stihl 82R and 82T’s. The extension hedge trimmer looks a little better but still unsure of blade quality. As far as the string trimmer attachment I would probably just use around the house and shop properties. Don’t think it would last on a trimmer rack in the elements on the crew’s truck. How do they compare to the standard 25cc string and hedge trimmers from other companies of commercial quality?
