Never Had A Problem!
I've never had a problem with SanDisk flash memory. The Price is right and the quality is good! Solid and reliable!!

Very Fast with all SLR
This memory chip allows you to take pictures mega fast at a high resolution. This is because the flash memory is so fast.

Good buy!!!

Bought 2 - they both work fine
SanDisk SDCFH-004G-A11 4GB/15MB Ultra II CF Card ( US Retail Package )
What can I say. I bought 2 for my new trailcam.
After 3 months out in the bitter cold, rain, and snow they both still work fine.
During that time the Reconyx took over 4200 pictures.

For use in my superior Canon Digital Rebel XTI
I use this in my superior Canon Digital Rebel XTI. It is amazingly fast. However, if this were in a nikon, it would probably break. Nikon cameras are substandard to Canon, and should only be used by people who are unable to grasp the concept of what it's like to take good photos.

Thank you!

WOW
A great compact flash, I bought it for my canon 400d and it works flawlessly
