Summary: I have always liked ScanDisc, so this was my first opportunity to use the Extreme SD Card & I can't be happier for the processing speed when out taking general pictures. 4G is perfect on vacations & general usage for daily opportunities.
Pros: Easy To Use, Great Value, Love Scandisc, Reliable Performance, Writes/Reads fast
Summary: I just transferred 2gb of files onto a new pny 16gb class 10 micro sd in under 10 minutes. my 8 year old gateway 838GM could not read the 16 gb micro sd with an SD adaptor so I bought this reader and it worked immediately. The 2gb of files had taken about 45 minutes to load onto the pc from my old 2gb class 2 micro sd with the SD adaptor. What a difference in speed!
