Youssef Mehdi –
My package did not come with a 32gb TF card or any card at all for that matter. And the car charger is 4ft not the described 11.5 ft which is weird considering this product isnt cheap

The camera quality for the cameras are pretty good. However, the rear camera is pretty useless in the dark. I have three problems:1. The 32GB SD Card that comes with it started producing a read/write errors within the first week, so recording won’t work unless I replace it. I get that SD Cards will inevitably fail when continuously recording, but having it crap out in the first few days is a real bummer.2. The device occasionally stops turning on. The fix for that is just leaving it unplugged for a few hours before it will turn back on.3. There is no option to flip the image for the rear camera.I ended up just uninstalling it. It’s great when it works, but pointless when it doesn’t. Can’t honestly recommend this, but I’m sure majority of buyers will be happy with it.
