The unit that I purchased never worked from the time I took it out of the box. Specifically, it never tracked the action (Basketball). In addition, it constantly disconnects from Bluetooth, resulting in a bright blinking light that detracts players in the court. Instead of simply returning it for a refund, I made the mistake of working with tech-support. I uploaded many files, followed all of their requests and instructions to help them troubleshoot and improve the solution and device. I spent many hours working with them, all to the benefit of their company, but getting nothing in return. I finally said that I was going to return the unit, and support told me that they could handle the whole return and exchange on their end. I also believed that, and that was also a mistake. After several weeks of being promised, the new unit, I have not received any updates. Product functionality and support have been a major disappointment. I know this product works for a lot of people, but not for me, and they are not doing a good job of standing behind their product. I hope others have better luck than I did.
