Impressed with the power and performance with this tool. It will gnaw thru very thick brush and saw thru garden variety hedges with ease. My only complaint though not a deal breaker would be, the trigger needs more of a quality engagement, it was a little finicky sometimes when I squeezed the trigger I had to pull it all the way to the on stop to activate, almost like the contacts were not going to touch and left me wondering if they would on down the line, time will tell, EGO BETTER TRIGGER PLEASE. As for long term reliability Time will tell, only used 2 times. Over all a great tool to own and you will never go back to corded after using this EGO trimmer!!
