Used the EGO 56 volt cordless trimmer. The lithium battery lasts approximately 40 minutes, and takes the same amount of time to charge. I just swap batteries and keep going.
I have Ugly Line and Heavy Duty Twist line.
This is the first electric trimmer that I have used that works as good as a gas trimmer.
Followed up with the EGO handheld blower.
