Really haven't had the chance to use it. Bought one for my grandson's Birthday and one for my self. We get snow in the winter and sometimes the trees fall on the lines. Thank you, E., North Fork, CA

Pretty great so far, I've been using it all week and haven't had to recharge it yet. Obviously recharging it would take a long time, it's a huge battery, but welpl worth it.
