I bought this for my Lumix FS35. 30mb per sec is great for video capture and the card is such a low price for class 10. I have had no problems with write lag or file corruption as you might usually get with cheap cards. Be aware you may have to format the card to suit your camera's firmware (I did) before it will let you record video - you can usually do this from within the camera menu. This is not Play's fault, just an FYI. Generic cards won't come formatted specifically for your device.
