The correct and accurate way to adjust the height on any table router is to lower it then bring it up slowly to the correct position. It's a bit like adjusting the old mechanical kitchen clockwork timers, for five minutes simply turning it clockwise to the five minute mark is hopeless, one winds it at least half way clockwise then anti-clockwise to the five minute position. I think you will be VERY happy with the Triton TRC001, but don't forget to remove the spring, a very simple job.
