I have this camera for some months now. It works well, the videos are high quality and allow the identification of a number plate a few meters. The screen is very convenient to check the focus and access the settings. The charger is standard 5 volts, so replaceable if lost (personally I tinkered a trendy thing on the ceiling). The start / off mechanism with the contact is handy too. The suction cup is bulky, the camera finds herself in the field of vision, but not the choice of another sucker. The default because there is one, this is the video: the compression method is ancestral (mpeg 2 I think), suddenly the videos are too big: an SD 32GB, I store 5:00 driving in standard size. While the files are run cyclically (the former are erased), but it must quickly make a backup if necessary. It's a shame I did not ask the h.264, but still ... Conclusion: good and effective camera, a bit expensive in terms of its shortcomings.
