Rating: - Wrong product for me, but could be great for you.
My camera wouldn't accept this card but Eek Technology, the amazon merchant I purchased it from, took it back even though the mistake was mine. Check your camera carefully to make sure it can use this high capacity card. If it can, I'd suggest you take a close look at Eek when you are purchasing.

Rating: - You're nuts if you don't buy this.
This is a name brand high capacity flash memory module and it is selling for a very tiny price. What could be better?

I'm using mine with my Canon Powershot A580 camera and can also use it to store net downloads and general PC file storage. It works just fine with rapid high resolution camera shooting (5FPS), and the same with motion picture camcorder - using the same camera. Of course I can use it for MP3 music recordings. I don't find a single fault. It appears to be the best of the best. Who are these people rating this great product as less than five stars? Thank you all for bringing the price down by publishing picky, picky, picky, reviews. I'm buying more.

Rating: - NOT compatible with Canon Powershot 590IS
The Sandisk site says this disk is compatible, and the user manual for the Canon Powershot 590IS says the camera can use SD or SDHC memory cards, so I assumed this card would be compatible. It wasn't. The camera says "memory card locked!" even when the card is unlocked. I'm giving this a one star rating because everything I looked at says this card is compatible, but it wasn't. For the Sandisk compatiblity site (which, of course, recommends their most expensive 32 and 16G cards first), see http://www.sandisk.com/Compatibility/Device(8725)-Canon-PowerShot_A590_IS.aspx . I haven't found a site so far that specifically recommends one card over another for this model of camera.
