I thought I was ordering the SanDisk Extreme SDHC card, and instead received the SanDisk Extreme HD Video SDHC card. It looks like SanDisk previously made a card entitled SanDisk Extreme HD Video that was 20MB/s and Class 6, which is what people in other reviews are complaining about bait and switch, etc. If I had received that, I would be very upset because it is lower performance. However, the item I received is a newer version of the SanDisk Extreme HD Video card, that is 30MB/s, Class 10, and supports UHS-1. What further confuses this whole situation is that SanDisk's web site is very much out of date, and it's not even clear which product lines they are shipping or not shipping right now. My conclusion is that although I ordered a different product, this product may be better because it supports UHS-1 as denoted by the little "I" next to SDHC on the front of the card (not shown in the photos for many SanDisk Extreme HD Video cards). Luckily, my Nikon D7000 supports UHS-1, but some cameras do not. Bottom line: be very careful shopping for SanDisk SDHC cards on Amazon as the photos, descriptions and items shipped may not match up. In my case, all 3 were different! I give Amazon 1 star for all of this confusion which is easily cleared up. The support rep I spoke with did not seem very interested in fixing the source of the problem.
