anyone use them? I always thought they were a joke until I saw one in operation this morning. We need one around the house for light duty work. Great Christmas gift for my wife

. She's wanted a corded one for a long time becausse she is tired of sweeping out the deck for the kids.
I have a ton of Milwaukee batteries that will fit their blower but this Stihl I saw this morning generated a lil' hurricane. Anyone know what the operation time is on them?
