Have the card for my Qumox SJ4000 bought. Perhaps there are even more favorable options, but after that I did not wanted. I have a Qumox camera, so I wanted a Qumox card. I thought, then everything is certainly good.
This is still the case. The card can be super describe from the camera and is recognized using the supplied adapter both in my PC and my MAC and the videos and photos safely arrive on the computer.
