I bought for one-time work, for working with stucco. Actively used for about a month. He mainly worked with a flexible shaft. The device proved to be worthy, very. Compared with Dremel, definitely not worth overpaying for the brand. But I bought all the nozzles from Dremel. Has some pros: Price-quality ratio. A rather light and high-quality device, surprisingly quiet, good equipment, a suitcase, a flexible shaft included. I really liked the collet chuck, it’s convenient to use, you don’t need to use a key (especially with active use, when nozzles have to be changed often). Some cons: At low speeds, it is rather weak, there is not enough torque, a weak cartridge, the shaft is not lubricated, those nozzles that were needed for work-curves (grinding), of course, saved on all special stages.
