I ordered this tool because I wanted a "motor" with Dremel flexible and some accessories without ruining me. In this sense, I am very satisfied. The accessories are a set "basic kit" which allows for an overview of all of the accessories brand boxes. Depending on your needs, you can equip you for this or that specific application (drilling, polishing etc.) My little restriction on the on / off button that also serves to speed adjustment. I would have preferred two separate buttons. We will now judge the tool on the medium and long term ... I urge you to buy at the same time universal chuck which is absolutely essential to simplify changing accessories and allows the use of non-Yamaha accessories.
