Also under Windows 7 (32-bit) without problems

Actually, a card reader on all operating systems should work well - you'd think. Nevertheless, my "old" bitchy even under Windows XP, reading cards was as a gamble, and often possible only after a restart of the computer. So I got myself before buying this card reader that okay by Ultron that this reader under Windows 7 (32-bit) works (the e-mail response from Ultron actually came promptly). So, does the 75-in-1 actually properly, tested with some SD cards. Also good: The solid metal housing with threaded holes that do not tear as fast as plastic housings, if you purely revolves only a tad overtighten the screws. I am fully satisfied with the 75-in-1 reader, although I'll certainly never try out all 75 cards variants.
