I have an EGO and absolutely love it. Lots of battery power. I also have the EGO leaf blower, it too is an excellent piece. My Brother in law liked my setup so much he bought EGO items for himself. If I were to buy again, there would be no choice, it would be EGO. I have not noticed the ergonomic issues noted above, nor do I need two hands to run it, and nor does my Brother in laws unit. Mine is 5-6 years old, Mike's is 2.
This is the model I had. I also remember that the battery made it top heavy and hard to keep the front wheels on the ground. I wanted to like it but it turned me off on these. In 1969 I mowed with an electric mower, but it had a cord...LOL..
