I cant stand them at all. The light they put out is so harsh that my eyes will start to hurt after a bit. It doesnt look natural like incandescent blubs.

If I have to use nothing but CFL bulbs in my home, I'll never be able to read in the evening with the lights on because of the harshness of the light.

I also do not think that people with visual problems, like a lot of us MSers have, should not be forced into using CFL's.
