No problem with the quality Fein, I use regularly for almost a year, compared to other brands. The downside, however, about the length of use: as the Multimaster 350Q is a racing machine, its accessories do not last the expected time (valid for all Fein accessories). We must therefore buy regularly. The blades wear out very even too fast, but the biggest flaw comes from the velcro which is not resistant to even oscillations that the abrasive is still able, even by reducing the speed of the machine. A bit annoying ... Anyway, the work up for the durability of the product. That's why I removed one star in my judgment.
