It's clear that you're very positive about your Panorama2 dashcam and that's OK of course. Good that you made the right choice and that you're glad with your dashcam.
However, to claim that having two power sources, 5V mini usb (for power from cigaret lighter) and 12V for firmware upgrade is an advantage, is of course rubbish!
This way you could call every function or option from this dashcam an advantage, compared to other cams....
Sorry, not to attack you, but this is my opinion.
Yes, I am positive about Panorama2 and it's deserves it. My positivity does not come out of no-where, - all advantages are justified and proven within this thread by me and other people who bought it.
I am also positive about ANY other dash camera or other products that truly deserve pointing out features / options. For example: Lukas 7900 can run 128gb memory card, available to connect to OBD2 ( I like this option very much, but it all comes at extra price of course ), can use CPL filter. Same as I like some Mio and Finevu series uses CPL filters. Papago was one of the first who started using Lane Departure Warnings system. Some dash cams can warn you if you driving too close to front moving car, etc. More and more new features added to modern dash cams and if any of them are truly useful in real life, then of course it is an advantage.
You probably don't know difference of mini-usb and micro-usb ?!
Few real life examples why having micro-usb port is big advantage:
1. Person recording a trip, visiting friends, taking dash camera out from car into their house, using these days common mobile phone charger can playback video on dash cam at home. Or connect via AV cable to big screen TV for video clips playback.
2. If somebody want to see how their pet spending time at home when they are away. They can set panorama2 on motion detection recording, for power supply connect via mobile phone charger. Later will be able to see how dog / cat / mouse / hamster spent a day. What time eat, what time took a nap, took a crap, etc.
3. Newly-born babies laying in their bed ( cot ), they always making funny faces, making funny sounds / trying to start talking, etc. Again you can use panorama2 with motion detection to record all interesting stuff and again for easy and quick power supply can use 5v micro-sub port to connect via mobile phone charger.
and so on ...
There are many other situations where having micro-usb on dash cam is advantage, so I don't see any reason why you call it a crap ?!
Best if every individual person decides for him-self about any feature of any dash camera, - is it practical for him / her or not.
