Buying second-hand
£380–520 used. Always insist on the original EGO battery (count the cells through the charge ports). Aftermarket batteries break this mower. Test runtime — a healthy 5Ah does 35–45 minutes; anything under 25 minutes means battery is gone (£200 to replace). EGO retain value better than any other cordless brand.
