This keyboard had one job: Stay connected to the computer. All other functions are secondary, as no connection means it is totally useless.
Thanks to the wonders of BlueTooth, the worlds crappiest wireless technology, connecting (and re-connecting) your keyboard is likely to be a pain. Microsoft has chosen to do things differently than every other BT device ever invented, by doing away with a pairing mode. Is it ready to pair? Who knows!
In another stunning move, they decided that knowing the battery level of your battery-powered device wasn't an important feature. You don't even get a 'low power' warning. The keyboard simply stops working when it is time to charge it.
Speaking of charging it, the lack of battery level means you get to play another fun guessing game I like to call "Is it actually charged yet?" After leaving mine plugged in overnight, the answer today was 'no!' 14 hours isn't long enough. I got half a day of function, only to return from a trip to find that the keyboard was unresponsive.
The flashy feature on this keyboard is the fingerprint reader, and it's neat until it quits working without explanation. The funny thing is, when it did work, it always took longer to use than just typing in a PIN. First, you have to hit a random key several times to 'wake' the keyboard from its battery-saving slumber. Then you get to press the fingerprint button in the hopes that the keyboard is actually awake and ready.
And speaking of sleep, this keyboard conks out after a few minutes, at which point you need to press a key repeatedly to wake it again. But wait, there's more! It often wakes with a modifier key 'stuck.' You learn all kinds of cool things that happen when your shift key is secretly being held down. Loads of fun!
-Keys feel and type just fine
-Lock key, cool!
-Clear key on keypad, cool!
-Dedicated calculator key, cool!
-Dificult to connect sometimes.
-Totally random battery life (works for days at a time, then can't seem to hold a charge for half a day)
-No battery life indication in software or hardware that I can find.
-No back-lighting. Kinda stupid for a keyboard this expensive to skip on that.
-Sleep/wake problems that really slow your workflow down.
