Excellent choices! I'm glad I have purchased the cards. The price is excellent, the quality is excellent, saved a lot of money. Couldn't be more happier on this purchase. I would recommmand it to anyone that need a 4GB SDHC SD 2.0 SPD.

So far so good. I have lots of space on this one and for the price it is a steal!

I purchased the product since description said it will work on "Casio Exilim Z1000/Z600/S600 cameras". when I put it in my camera, message said " card error ".

I was not sure what card exatly to buy for the Nuvi, but am greatful to share that it works perfectly with the Garmin Nuvi 360 GPS.

I have been using Panasonic SDHC Class 6 4GB cards, and have been pretty happy with them. I decided to get this one just because of the low price and high ratings, and am pleased to find that I agree with the many 5-star reviews.

Some information I didn't see in the other reviews, in case it's of interest: I ran a write test with a big file on my computer, and saw write speeds consistently above 6MB/s, as you ought to expect for a Class 6. (Among other things, that means of course that your camera can get ready for the next shot just that much faster because it's spending less time waiting for the recording to be completed.)

I didn't bother with a read test, since read speed is rarely an issue.

A comment on SD card readers/writers. As many have said, older SD devices, including older cameras, will not work with SDHC cards. My old card adapter (Sandisk 8-in-1) hung when I put this chip in. But my newer adapters (a built-in slot, and an Edge All-in-1) worked just fine. So if you're having trouble, this is possibly the first thing to check.
