IMO the Bosch quick change is a badly imagined gadget. The implementation of the bad idea has been so poorly executed that it should be cursorily dismissed as an option. The quick release gadget does not hold the bushing adapter gadget in a secure fashion, so even if you think you have centered the bushing, the bushing and the bushing adapter gadget move around in the quick release gadget.
I own the gadget, I have tried the gadget, and now am looking for a practical store bought solution. As mentioned above, I have yet to find an aftermarket base plate that is a good fit on the Bosch routers. A week ago I asked specifically in this forum for suggestion about a suitable store bought product, the only applicable suggestion I received was for a plate that I had already identified as a possibility, so I bought it and found that it did not fit well. It fit but not well enough to make it useful.
It appears the Makita RF1101 may actually be designed and manufactured with the factory equipped parts that permit the bushing may be precisely centered.
I am hoping a router enthusiast with some first hand knowledge of the actual tool I am inquiring about, may be able to confirm or correct my impression that the factory OEM base may be centered properly.
