Its service quality is good. I have been using Coolpad note 3 since few months. I faced few issues with it in the beginning. I visited its service center. They were too quick and resolved my issue in one day.
It is a good option at this price. It is powered with a very good processor, huge RAM and Cams must also be good. But battery capacity is very less. I feel Redmi 3s Prime is a better option at this price.
