Input:
I looked at the other reviews here and bought this with a 256MB card and a Canon S30. I run Win 98 so anticpated no major problems. However the CD crashed my system, botched my email for a week and even then would not uninstall. After a week of frustration and intermittent working (when not crashing the system) I finally managed a complete uninstall by having to manually delete the folder from my C drive. My email subsequently worked, but on reinstallation the reader still would not work. I then uninstalled (success first time!) and downloaded the driver from the Sandisk website with (so far) success. The driver has worked twice with only minor problems (which may have been due to me removing the card early as the Eject command is not present on the new software, but I am contacting SanDisk about that).
So in summary - OK, but what a hassle. If it still does not work or wrecks email again it is going back.

Options:
A: very positive

E: very negative
Answer: D: negative
