I tried out the 20volt. Was not impressed. The trimmers I use are both redmax bcz2660s. I know gas vs battery no comparison. I wanted to try it for comparison purposes, and if it was decent I would use it as a back up. Here is what I found... line was way to thin for me (.080). I run .095 Kevlar reinforced. Felt out of balance, and way too lite. As others have said it bogged in longer, thicker grass. Because it was so light I could not get a consistent height on the grass. Had to go back over it with my redmax. Overall not a bad producthing but just not for me at this time. It and the other ope that dewalt makes do have there place. I may try again in the future, but for now itso the beast called redmax that I will use.
