If you don't register, you can't know whether your piano is genuine or not, and you can't guarantee it after sale.
After registration, you can check whether the product is genuine or not. After successful registration, you can get a membership card and a WeChat red envelope, and you can also get an electronic modulation card, which is more convenient for after-sales protection.
There are a large number of Yamaha refurbished and fake pianos online and offline. In order to protect the rights and interests of Yamaha customers, remember to register and buy Yamaha pianos in official website.
