None for my camcorder
No, I would not recommend this to a friend
I bought a JVC HM-100U HD camcorder that requires a class 6 sdhc card. I ordered 2 of them for the camera and much to my surprise they were not compatible. I did some checking and found that some of the lesser known brands are a class 4 labeled as a class 6. I learned a valuable lesson that cheaper is not always better.
