Garden is about 12m x 15m, mostly lawn but with flowerbeds, trees etc in the centre (so a lot for a cord to get tangled on).
I was very pleased with my cordless Gtech lawnmower, but the battery has only lasted a year and it’s £150 for a new battery.
Gtech says that’s a normal battery life, so I don’t really want to spend £150 per year on new batteries.
I can get a decent corded mower for about £80 (Flymo Speedo-mo), but will I regret it when I’m having to trail the cord all over the garden?
