BEWARE! AMAZON USES HYBRID DHL + USPS TO SHIP!
The card was ordered over a week ago and has not arrived. Paid for 3-5 day shipping. We tracked the order and found out that it was delivered NOT to us, but to our state Postal Service!!! From there, DHL said, because of a crazy partnership between DHL and the USPS, the USPS will dilly dally its way toward us. We have to wait another FEW DAYS!!!! So when you pay for shipping, BEWARE!!! You are not getting the card until AFTER a SECOND shipping period determined by your state Postal Service!!
Thanks, AMAZON, for a crappy shipping job.

It may be Class 6, but it's still slow
I bought this Transcend 16GB memory card to use in a Canon HF100 camcorder. I think Amazon even recommended the pair. And the price was right.

Unfortunately, this card is slow. When I turn on my Canon camcorder, I have to stare at a message saying "READING THE CARD" for 10-15 seconds before I can take a picture. The wait to take a movie is better, but still 4-5 seconds.

I tried my old 2GB Sandisk Extreme III card, and it is at least TWICE AS FAST, so I may have to send this Transcend back. Waiting 3-4 seconds is OK, but 10-15 is awful. I'm missing shots. I also need to see if the Transcend can keep up with 17 Mbps video mode. It claims to be "Class 6" speed, but maybe it's slow at random accesses? Frustrating.

Good Card, Good Price
Just bought this card and love the capacity for the price. I've been using it for two weeks now. As of yet, I've had no problems of "failure" mentioned in some of 1,2,3 star reviews. For the most part, memory is memory and if you're card is going to fail, it will. It doesn't matter which brand it is - it will fail. So save some money.

works as expected
I picked up a pair of these through a deal on another website. I use them in my new Canon HF-100 camcorder. They're SD cards, it's hard to 'review' them because they operate pretty much all the same. The card itself seems to be made properly. It's not 'indestructible' but doesn't seem any more or less fragile than any other cards.

The reader is a little unusual in that the SD card sticks out the side of it, not the end. This won't be a problem for most folks but it may be worth considering, especially if your USB ports are jammed up close together or alongside other occupied connections. The back of a PC might be a bit tight if there's lots of cabling already there. YMMV, of course.

If you get a good price on it (mine were around $60 each) then it's worth considering.

Watch out, cheap memory may come back to BITE YOU!! I/O Error!
Yes,

This producted worked well for the first two months. Then, today, I tried to upload my Kentucky derby photos and videos and I got the infamous "I/O reading error". Basically means, the card is broken.

I tried EVERY means to reformat the drive. From PC reformat to manual CMD reformat, nothing worked!!

Thank goodness there are great memory card recovery programs, or else my precious Derby moments would have been lost, but WATCH OUT, don't get stuck in the safe mode of thinking. This error may come back and bite you .

Spend the extra money and get a good brand.
