I just ordered them for an OF1000 router, expecting delivery on Monday. As far as an edge guide, I use them quite a bit. I've had good luck with my Bosch edge guide with micro adjust. It gets used for fluting, dados, and grooves quite a bit. There is no reason the Festool with the micro adjust shouldn't be just as useful. OTOH, I'm not sure about the guide stop yet. It may see some work for dado and groove work. I'll let you know after they arrive and I've had a chance to try 'em out.
