I got this because I needed a small and light dashcam to go on the rear window glass of my wife's crossover. You can't use a suction cup mount on the rear glass because of the heater elements - it just falls off. So this one, with its adhesive tape, works really well. Its lens angle is just sufficient to be used on the close-to-vertical glass, and because it's light, I don't think it will fall off (unlike heavier dashcams I've tried to attach with double-sided tape). It comes with a spare piece of tape. Easy to set up; I'm not convinced that the image quality is as good as some more expensive dashcams, but it should be good enough to document a collision.
