The jacket arrived fairly quickly, within the specified time. Good quality, but there are threads hanging here and there that make it hard to close the zipper. This can be fixed quite easily. Overall, it's forgivable, although I would like the manufacturer to take note, since I'm not the only one who noticed this. As for the size: I'm 176 cm tall, weigh 92 kg, and have a bit of a beer belly, so my usual L fits just right and I can even wear a sweater underneath. The sleeves are a bit long, but there are Velcro straps, which make up for that. If you have these measurements but a slimmer build, take an M. It will be just fine. Also, the zipper is on the right, which is unusual, but you'll get used to it.
