I had an old mower this brand whose plastic clogs were broken. considering the price of shoes, I bought a new one of the same mark for a fair price a bit higher. this new mower, the shoe adjusted by a knob, which is very comfortable (more hoof breakage risk) and that's fine as setting (1.5 min). Cons: - Power cut a little low (for my taste) - The manufacturer says it is already necessary to charge it before each use (for 8 hours) and that should not be used directly from the mains, which is a bit limiting. otherwise a good product cheap and that should last.
