Yes it works very well.
But I have some comics with page number to the bottom.
As result, I can:
1) leave defualt setting, automatic crop to top, left and right (no crop to the bottom), with wrong image proportion, too wide (circle are oval...)
2) force calibre to maintain proportion of image, but the image resulting is too small, and with sony reader text comic is very difficult to read...
So, manual cropping (forcing cropping also for the bottom, removing page number) could be very useful
