I I Bought this item because I have two very similar cameras that have been rebranded under a different brand (Gear Pro) but are effectively the same camera. They were pretty decent quality, especially for the price, so I went with these because they had an extra "high speed" option. The product description does not mention a "high-speed" VGA resolution option, which corresponds to a video recorded with a solar-powered calculator. That was annoying, but not decisive. The real hurdle was the fact that the battery refused to hold a charge. I've tried charging it with several different chargers and USB cables, different outlets and different times (from 30 seconds to 2 hours) with no success. I can only control the camera when it's actively connected, which means the best I can do is use it as a DVR and not as a standalone device. Even when working with the dash cam, it often took more than half an hour to turn it on, and 50% of the time it got stuck on the loading screen. The only way to fix this is to let the battery drain (which luckily doesn't take too long). Since the purchase was so cheap it wasn't worth fighting customer service to get a replacement. block/battery. My experience with this camera is not very good and I would not recommend it.
