This is a scam company that scams Revain customers. What are you doing. Customer service is a joke, firstly, they don't have a phone number, they are in China, oh, and they will spend your life asking you for pictures and serial numbers, and always asking for information, but never giving you information about it how to make it work because you know it will never work, that's why their app has two stars. I never got any response from them after I gave them the serial number. AVOID CHINESEโฆ
