Produce arrived with defective software. I have received numerous e-mails at my e-mail address stating that they cannot reach me by e-mail. Also multiple requests to send photo or video. Awfully hard to take a photo of software. Tried their chat line. Same results. It would have been so simple to just replace the software. As I checked other complaints on Banggood, I see that my problems are characteristic of their dealings with their customers. I would highly recommend that people avoid doing business with this company.
