Pros: I haven't measured it, but this card dumps the buffer of my D7000 quite fast. While rated at 35mb/s write, they seem significantly faster than Sandisk 30mb/s cards. They compare well to the Sandisk 45mb/s cards. Currently they are selling for less than half the price per mb than the Sandisk 90mb/s cards, so I'd say they're a danm good deal right now.

Cons: Not available in 64gb or bigger.

Overall Review: I would never have bought this card, but I needed it in a pinch and got a pair of them locally. I'm quite impressed! If money were the primary concern, I'd purchase more of them. Since speed is slightly more important at the moment, I'll probably go with Sandisk 90mb/s cards in the future. But if you need relatively fast on a shoestring, these do the trick! If you're only familiar with slow cards, they'll turn a camera that can utilized the speed (D7000 or 7d) into a much faster beast.

Pros: Moves a lot of air with minimal noise.

Cons: Doesn't last. This is the fourth one of these fans I've owned. The first two I had failed, but I was able to peel the sticker off, lube them up again, and they've run about...how long have they made these? That long. Still going as of 6/2015. The second two have been nothing but trouble. And you can't oil/disassemble them. Oh, and they leak some sort of oil when they fail, so DON'T put them on top of a case! Glad they didn't destroy my rig!

Overall Review: I'll be looking for a worthy replacement. I don't know if anything else in this form factor that can move this much air. But pretty much any fan I've used would be more reliable.
