Query: Poor Quality

I hadn't used the 400 XPR more than 5 hours over the course of a year to cut lightweight materials before it burned out just like many other reviewers have experienced.Since it was out of warranty I decided to take it apart to see what went wrong. The entire construction of this tool is worthless. The housing for the brushes is a poorly fitting plastic fitting that comes loose from the motor case, this tool is hopeless.Save your money and look for a new brand, Dremel does not produce quality tools anymore.If I could, I would give this 0 or negative stars.
