I have the 694VS kit comes with the case.
The 690vs router has a dial.
One thing I noticed right off the bat the 1st time I used it was that if I pressed the motor, (moving too fast or hard wood or both) the rpms dropped automatically and stayed at that speed even after pulling away.
I've had 2 690s since around 03, 1st died from composite decking both did this, rpm drop when pressed. It freaked me out when it happened the 1st time, I never questioned the shop I bought it from and don't recall ever finding anything writtein about it
