Two years ago I bought an E-Go push mower, and I really like it. Battery (56v, 5 Ah) has held up well and still does way more than my yard requires. I was going to buy one of their trimmers too, but I have an old Husky commercial trimmer that was given to me many years ago because it wouldn't run and would die when you gave it throttle. Cleaned the carb, replaced the primer bulb, and it's never failed to start since, runs like a champ. I only run stabilized ethanol-free gas in my equipment, got tired of cleaning fuel tanks and carbs every year and sometimes multiple times a year. I rarely run more than half a tank of fuel doing my normal trimming, but a couple times a year I help someone out and will run multiple tanks through the trimmer in one day. If I had an electric, I'd be waiting for batteries to charge for sure. My neighbor has an electric, and it's realistically not much quieter than my gas trimmer. The mower is stupid quiet, I could mow at night (it has headlights) and no one would notice. I still get looks from cars passing by, they see me pushing the mower, but there's no noise, I think they think I'm just out there pushing it around with it not running.
What I really want and can't justify is a backpack blower. E-Go makes one, but apparently it eats batteries pretty quickly. Even the handhelds don't last very long, definitely not long enough to get all my leaves done in one go.
