Driver Issues on Windows
Board works fine once drivers were installed, but it was not plug-and-play for me. Make sure you have the correct USB bridge driver ready.

Great Value Board
Good hardware for the price. I had to install drivers manually on Windows 10, but once that was done, uploading sketches was smooth.
