If you are purchasing this you likely have the technical skills required to locate the CH341A programming software and successfully flash your chip. I bought the latest version 1.34 from skygz@qq.com as per other reviews. It worked exactly as expected and successfully flashed firmware version 3703 on my Asus Z170-A BIOS chip. The chip itself was a Gigadevice GD25B128CPIG, similar to the GD25Q128 series chip listed as compatible. I can now use my computer again after a buggy BIOS update from AFUWIN made it unbootable. It was worth the money.
