I don't recommend buying this programmer. IF YOU BUY IT YOU DO SO AT YOUR OWN RISK. The driver software doesn't work. Don't throw your money away. Don't buy it.
Soft for this device works only if the default Chinese interface language is set in Windows.(in English interface and any other - error) It's not in the description. As there are no links to drivers and soft. Because of this, negative customer reviews - many could not get the device to work at all.The device is good, you need to fix the software.
