Ease of use is relative for this type of product, isn't it? Hopefully you've already stopped double-clicking on hard drives and relying on an autoinstaller when buying a product like this. But it worked as expected. If you're like me, you probably choose this to try and fix your bricked Chromebook. I'm happy to report that this worked great for this purpose and I unlocked a faulty Acer Chromebook firmware. Just follow the instructions in the email and you'll be fine.
