Cutting guides are quite large (it loses some maneuverability during use). The plastic tabs that appear on each side seems to be fairly fragile, as is often the case.
Level performance, nothing to say, the precision is at the rendezvous. You can use the device on AC or wireless (with an appreciable autonomy). Too bad no cover or case is provided to store all accessories because the box is not practical.
Overall, this mower fulfills his office with performance consistent with the description.
