More than I expected!
First of all, this was the best deal I could find online and offline.
It shipped super fast, and it works very well, and the seller communicates well!

Works for the Blackjack2
I bought this here at Amazon for the BlackJack 2 and it totally works. It reads as 7782 disk space which is still cool. I was able to put any files (music, video, etc.) and it was fine. I deleted/transferred multiple times and it was fine. It definitely is the size of my pinky finger or less so be very careful that you don't lose it. I too can't wait for the day when there is a 32gb because I heard that may still work for the Blackjack 2.

Satisfied Cutomer
I purchased this for a my Samsung Instinct. The device shows the full capacity of the card (7788 Mb) and works well. Ordered from Netweb who promptly shipped it and received it in 3 days.

Good size for the money!
I have a Blackberry Curve with the beta version of OS 4.5 and I used this 8GB microSD card and I now have a portable "flash stick" with me all the time. I carry my Blackberry everywhere I go and sometimes when I need to copy a large file, and I forget my 2GB flash stick, I can simply just transfer to my 8GB in my Blackberry. Just remember, this will not work in the Blackberry OS 4.2 - you can only go up to 4GB max. Make sure you upgrade!

Works well. Needed a new card reader though.
The 8GB card works fine with my digital camera. However, copying files larger than 300MB (video files captured with my camera) did not work using my old card reader or the camera's USB cable. I tried on my desktop and laptop, neither worked. I bought a SDHC card reader at a local store for about $12 and that worked out fine. Maybe it was just me, but if anyone else runs into this problem while moving large files, a SDHC reader will solve it.
