I bought a DeWALT DCD701D2 F7B9B model I have nothing to compare with, before him there was a Chinese. But overall I'm happy. The buttons have precise fixation, the Start button has a proportional response (in Chinese it was either twisting or not, and the rotation speed was not regulated) I ordered a DeWalt DWST1-71228 box without a lid for it. As the lid will act as a case from Shura. I think this is a good option
