I was able to use it only twice and then afterwards, my macbook can no longer detect it.[...] I am simply disappointed in this product. I should have checked out ALLl the reviews about it including blogs abour how it did not work with other users, too..

getting harder to find

By

from a place far, far away  -  Semi Pro

love the extreme line of memory cards from sandisk. i'm just sorry the smaller capacity, high speed cards are getting more and more difficult to find. i still find it helpful to use the 4gb cards for all day shoots and swapping them out for a fresh card for the next day.

The new Extreme IV is 45 MB/S, faster than the earlier version. I own both versions of the 4GB cards. I have never had any problems.
