For the most part, I've been pretty happy with my electric mower. I now have a second battery, so I can charge one while I'm mowing with the other. It's quiet enough that the noise doesn't bother me and I can even listen to podcasts while mowing (something I could not do with my old mower no matter how loud I had the headphones). My primary complaint would be the blade itself as the company (EGo) designed the locking mechanism so that only their blades can be attached to the mower. Unfortunately, I do not feel that their blades are of the best quality, and they have a strange formation that makes them very difficult to sharpen. All told, the mower is light, easy to use, and has worked well on our yard.
It was getting a little cool and dark (which is a little weird after a being used to a brighter summer) and the neighbor dogs started barking at something, so I decided to end my mowing before getting to the entire lawn. Considering that it turned out that the dogs were barking at a moose and her baby, I feel justified in my decision and not at all lazy or cowardly (like I kind of did before I saw them). Oh well, the rest of the lawn doesn't look that bad anyway.
