Summary: Because of the extremely low price and my unfamiliarity with the brand, worried especially about a slowdown in the speed between shots. It works great. No problem with compatibility or speed or quality of the shots. Gave it only 4 stars instead of 5 simply because I have had it such a short time. Would definitely recommend it. Excellent buy.
Excerpt: Pretty fast card, bargain price. Served me well so far. I've only had one little scare this week - camera displayed an error message about the CF card while reviewing photos and videos. Restarted the camera and it works fine. First time ever this happens, hopefully the last.Would recommend it.
