I have had the EGO for three years, very impressive. I have cut for. 90 min on one battery.

I also have a EGO mower, blower, trimmer/edger, hedge trimmer. No longer need to keep up with mixed fuel and the batteries interchange among the tools.
I have the saw , blower and self propelled mower and all have been great
