I purchased the S900 model of dashcam. It arrived quickly and was well packaged. It was easy to attach to the windscreen on the passenger side, next to the rear view mirror. The recordings are very good, with exceptional night time clarity. I had difficulty reading the tiny font in the instruction booklet but went online and used the instructions online so no real problem. I had help from a couple of different members of support staff, both very helpful, knowledgeable and professional. The price of the dashcam was very reasonable and definitely great value for money.
