Knowing the risk, I bought it. It does what it says, but there is another issue:
While it is very interesting and useful addition to knowledge wheels (especially if it is battery-powered - apart from Parkside), in practice, as well as in foreign comments I read, it is dangerous, especially for someone who is not familiar with chainsaws. It is better to spend another 50 euros (even on a smaller Chinese one) to get an electric chainsaw or battery-powered one (70 euros for Parkside, for example) that is designed for this purpose (controlled start, brakes, protections, more secure), rather than as an addition. I am in favor of inventions and multitools, but in this case, it is dangerous. The instruction manual does not explain much, the handling requires a lot of familiarity - you will make mistakes before you finish it at the beginning, and you will constantly have to be mindful that the chain or another screw does not loosen. The front guard does not inspire much safety... in a photo I saw elsewhere, the loose chain tore it like a cigarette paper.
In summary, it is best to avoid it, at best it is a casual job, with great caution and risk.
