Let me start off by saying this thing impressed me with the first pull of the trigger. I'm not completely sure on run time yet but this thing does move some air for sure. Wet leaves off of my back porch not a problem.
Had this blower for only about 7 months now, and the battery only lasts about 5 minutes. If you have time to recharge for 70 minutes, my yard will take all day just to clear my driveway.
The power of this blower is great! Unfortunately the battery life is approximately a 10 minute run time. Not worth the money. I thought I hated pulling extension cords around but at least I can complete a job with my old blower.
