The upside of this router is too high to pass by. Price, bases, and accessories almost make this a must buy. However, there are major quality control issues: collet fit was too tight for bit, 1 of the basis would not lock. Since these seemed to be fit and finish issues, I ordered another unit. The 2nd unit didn't have any of the issues the 1st unit had. However, the guide screw did fit in the second unit. I am going to swap the guide screws and return the 1st unit.
