negative:
Mini-CD with instructions can not be verabreitet of many CD players
Device freezes often an even update brings no improvement since
SD card must be removed after each restart and reinserted, otherwise Meldeung "No SD"
Wifi is only sporadically
APP only briefly after restarting phone (HTC One XL) and Cam, after getting an error message
Conclusion:
Technically Alternatice, but the software is immature.
For my purposes not geeigent because my remote control via the APP is very important, so I do not ever stop.
