Bought for smaller hobby work the mills. So far I have only soft woods and MDF processed with the mills and am happy with the result. I can not say anything yet because I insets only hobby About the Halbbarkeit. But they are well suited. One should think about what you need the router in advance. Putting them daily at diverse or hard woods one, you should consider buying router from the higher price segment. It all depends on the area of operation. For the beginner / hobbyist find the set is very good in price / performance. The only point of struck me so far is the edge milling of the stop ring of the cutter may leave a groove that you must back out grind. Not a lot of work but a bit annoying. For this point (which may have but maybe something to do with my previous skills as a beginner) and the point that they are designed more to hobbyists on the quality, I take the liberty to deduct a star. But as I said, for hobbyists is really great in price / performance.
Should be noticed upon further use of other points, I will add it here.
