I have a Canon Powershot (this works in both SD1000 & SD1100) and this works like a charm in there. At standard 640x480 it says it registers more than 9,999 shots... Didn't work with my older laptop's SD card reader, but a $6 USB card reader adaptor solved that (definately recommended). Love the number of shots that fit on this & will fit about an hour of movie taken on the camera too. Can recommend this without any hesitation.
Great Card:
I have 3 of these cards - I am storing my CD collection on them in ape format. I have had no problems with the Transend cards and they work well in my Cowon D2.
Great Product Stellar Price:
WOW, I ordered two of theese cards for my new Canon HF Vixia 100 HD Camcorder, they work flawlessly! I was reluctant to purchase these cards because some folks report problems with read/write errors. I wonder if this is a "user problem" or truly a manufacturing defect. In the end I purchased them because for 12.00 per card VS. 49.00 for the Sandisk, i figured it was worth the chance...so far I am laughing all the way to the bank :).
Mega memory:
Fantastic value for the cost. I can put so much stuff on this SD card. Great companion for a PDA.
