I almost have the same keyboard. The difference is that it has a Fingerprint sensor. I got the Microsoft Modern Keyboard with Fingerprint ID EKZ-00001. Got it from eBay too. I received it without issues but after my daughter spill my coffee on my keyboard, the keys below became sticky, almost to the point that whenever I press the key it goes back up very slowly. I might just get a USB Fingerprint Reader next time and a premium backlit keyboard next time I purchase.
