I have never checked to see if the circle is properly centered, must do that the next time I take the mirror out.
The mirror is very easy to take out. But be very careful not to drop anything on the mirror.
1. Make sure you have the protective cover over the mirror, maybe also remove the struts for ease of handling.
2. Stand the tube upright on the floor/carpet maybe use a towel on the floor/carpet.
3. Unscrew the 6 small Philips head screws on the outside of the bottom cast ring securing it to the tube.
4. Just lift the tube straight up, which leaves the heavy mirror and cast cell on the floor, very easy.
