Went to pickup mine today. Set it up in 5 minutes, mowed the lawn in no time. Very impressed, lightweight, smooth, quiet and smart. Indeed the power seems to be distributed to the motor depending how thick is the cut which is probably a great way to extend the battery life. My lawn is about 1/3 acre with a mix of short and tall grass, I think I only used 1/2 of the battery capacity, I put the battery on the charger 20 min ago and it's already full. It definitely feels as capable as a gas mower if not more. Very well built, seems quite durable. Gotta get additional tools to work with my 5A battery :)
