It arrived earlier than expected and was packaged well. It was very easy to assemble, however it had some stickers on it to mark the wind speed side vs the wind direction side. They were incorrect on the unit I received. I assembled it and mounted it on the pole and the wind speed never worked. I contacted vevor and they responded very quickly. They wanted me to send them a video of the unit in operation, which I did. They responded back it was being sent to technicians and they would get back to me. In the meantime after watching other videos and carefully looking at the drawings in the manual, it became apparent that the stickers had been reversed. After switching the windvane and the speed cups everything started working. So my warning is don;t assume the stickers are correct.
