I haven't had any problems using this memory card with my Canon PowerShot SD770IS. I can take around 1,100 photos on the card with the quality set to 10 Megapixel.

When used with Canon G10, it created several corrupted files. I shot in RAW and after 15 shot, I tried to review and the picture shows up, took several more shots and when I tried to to review the previous picture that I can see before now have the big question mark on it and says "unidentified file". The card never left the camera! Took more pictures and then more files now has that dreaded questions mark.

When I got home and uploaded the files, those with the questions mark is now corrupted (has only 1/4 size, incorrect color etc).

I reformated the card several times, this same issue happened again.

I sent an inquiry to transcend USA 3 days ago and hasn't got any reply.

Card was formatted in camera several times before use. Camera works fine twith Kingston 6 SDHC 8GB.

If they responded, I might edit this review.

I would rate these 4g cards a 5 star but unfortunatly my ipac hx2410 does not recognize them. They work fine in my Fugi S7000 camera, but I can't download the pics onto my PDA. I bought them specifically for my camera, and they work fine there, but I would have to wait to download the pics until I can get back to my home pc. Still, a great price/value for what you get!

it works great for me! holds almost a 1000 photos on my camera and i haven't had a problem yet with losing pictures. the only con i could list is that maybe i should get more ;)

This card is for special devices that take a super high capacity SD card. I don't think the description had sufficient disclaimer because most SD cards are universally compatible with one another.

Now I'm out $14, have a card I can't use, and of course I can't return it because my kid tore the package open before we realized the mistake. Amazon can do a better job to prevent this type of mistake.
