Memory card is not here, so the test would have to wait a while until memory card was at hand. However, the insertion was a little hard.
With the included USB cable, the battery can be charged immediately and will hold about 90 minutes. This length has not been tested for accuracy.
The operation is not difficult, since not too many functions are present. There are video, photo and Auto function. The water-proof housing allowed to film or take pictures under water, and in salt water. However, this should be washed after use with normal water when used in saltwater. And most importantly, you should check at the beginning of the housing for leaks.
The video quality is ok, but does not tear off the stool.
Overall I would say it is more for older children (11- 14 years) who have their fun with it while cycling, diving in the sea etc. to film or take pictures. Serious aspirants for Action filmmakers might choose a more professional version of the same.
