yep, i have this one too. When i first got it, the two side buttons that lock the top lid down were jammed - bad plastic finish. But after a few tries, it freed off ok.
Apart from the plastic 'issue' that cleared, its great. I use it for SDHC and CF cards, reads very fast through USB3 compaired to 2.
I have this one from Transcend. Inexpensive. I've used it to read SD, CF, and MS Pro cards. It is speedy - so fast that the card's speed is the limiting factor.
Plugged in the Lexar, Bosh! Done. That was it. I almost feel cheated that I didn't have to do any more than that.
My Canon Utility for MXF import, leapt onto the screen as if on steroids, and displayed over 100 1920x1080i 422 clips instantaneously. This USB3 stuff is swifter than runny snot through a calendar!
Very pleased. Now, all I need is an equally stable, non-chokable NLE to edit on.
