No problems except the "lane change" feature is useless.

Within 3 hours, I had an answer back with the information I needed to correct the problem (had I read the manual, it showed the right port to plug in to)

I do have a problem with my first unit as it was accidentally bumped and broke the swivel mount.

Great camera for one direction use, no problem with it so far

Great night vision but problems!

I prefer the suction cup--no problems coming loose

After having a minor problem with the device (mostly my fault) I am more than happy with the capabilities of this device, it was easy to set up right out of the box and the recording capabilities with the 32 GB card give an extended record and save time.

only problem I had was when I installed the SD card and tried to remove it, it's not easy

Sometimes it tells me that I have changed lanes when I haven't, which is odd but not really a problem.

I replaced the SD card with 4 different ones none helped with the problem,also used different power plugs { power supply's}. Nothing I did solved the erratic shut down problem, from the short clips I had it gave good video performance equal to my 40. dollar Black Box G1W-CB dash cam

UHS-1 u-SD card _ {also works with Monster 32gb u-SDHC (SDUSA-0032-L)

It also comes with a 3M Sticky mount rather than the inferior suction mount
