Review on KOOBOOK CH341A Programmer Adapter Converter by Richard Gross

I purchased this item to unlock the BIOS on the Razer Blade 15 2020 Base to install macOS but after reading reviews from others I was unsure of the voltage supplied was appropriate. I'm writing this review to let you know that reading/flashing worked for me right away and on the first try with this programmer. I haven't used a multimeter to check the actual voltage and would assume it's YMMV, but I'm happy not to be able to report any issues with my Razer.
