Very good tool, delivered in its original packaging. As others have mentioned the assembly instructions is a bit "light" but even when this is achieved after some hesitation and much thinking. The use and implementation are very simple and extremely effective. The knives are much more resistant than would be predicted by their appearance and are resistant to some rocks encountered on the 850 m2 treaties. Finally use (like all scarifiers) the basket is anecdotal and requires manual removal. Only drawback the wire around trees. Long live the lithium battery! But that's not for today.
