I have a leaf blower, and I use it for about 5 minutes a week in the summer to clear grass clippings from walkways after I mow. I don't like being "that guy", so I pretty much run around the yard with it in order to finish as quickly as possible.

I know that the electric leaf blowers are quieter, but my neighbor's makes a high pitched squeal which bothers me more. I think that she has some sort of condition, because she's literally using the thing for about three hours a day. I don't know how many battery packs she has, but she runs it until it dies, swaps the pack, and gets back to it. It's not a huge yard, maybe 1/3 of an acre, but she is compelled to get every blade of grass off of her driveway.
