I bought one, and it does record videos well, and is relatively easy to install.
BUT... If I had to do it again, I would not have bought it. There is no easy way to share the videos. Thinkware has a "viewer" you can download, and watch the videos you took, but there is absolutely NO way I could see to save the videos as a movie to let others see what happened. I contacted Thinkware, but they essentially ignored me. I would caution everyone to go with the Blackview, as the support for this product is below acceptable.
