Hello, Yaman has a fake one, made in Guangzhou, so-called domestic machine. When the machine is charging, there are lights around the fuselage. The light source of the keys is also different. Guangzhou Machinery Japan Company does not recognize or support the warranty. Guangzhou Machine only supports the warranty of Guangzhou Company. When buying, ask the buyer where the warranty is. If the seller guarantees the machine, the warranty period is one year. Excuse me, if I need maintenance after one year, where can I go? If it is Japan, it should be a local machine in Japan, if it is a Guangzhou company. It is the so-called domestic machine. You know that.
