Bests & Worsts Reviews from Amazon

I have gone through 5, count them 5 of this model. 3 failed right out of the box! I had an older Dremel from about 1997 but sadly it was stolen from my shop. The basic design is flawed. The motor and switches get clogged and choked with dust and debris from everything I have tried to cut. The stop button to change the tips locks up. The on/off switch is so difficult to turn on and off I almost cut my hand off. I am saddened to see what has happened to the Dremel. Bosch seems to have taken a once great tool and ruined it. Same as they did for Skil. I am not trying to bash Dremel. I purchased the 3956-02 model and it works fantastic. Its just seems to be the 400-6 model. My recommendation is to skip this model and go for the less expensive Dremel 3956-02 model.
