Before the installation of the dashcam, I was very careful when driving, lest I should encounter the racketeer. Knowing that all my colleagues around me were using STsmart360° dashcam, I asked them for their comments, and they all gave me good comments. Therefore, I bought STsmart360° DASHcam. STsmart product is exquisite and high, with clear picture, which makes driving more convenient in the future.
