I absolutely love this Pro Signature Keyboard. It folds down nicely to reveal the Surface Slim Pen 2 - which is magnetically secured in the slot! It just snaps right in there! The keys have a great rebound and feel - much like a traditional keyboard - which I like. Great space between the keys. The keys do make a clicking noise (like traditional keyboards - but not as loud) so just keep that in mind if you are taking it to meetings. The Keyboard attaches and detaches to the Surface Pro easily and folds flat when you want to use it as a tablet. - 1st picture has the pen hidden, 2nd has the pen tray shown, 3rd has it folded behind the Surface Pro 8 - to use in tablet mode.

This keyboard has a very regal look and the keys feel quite nice even during long typing sessions. The charging slot for the pen is very convenient because it helps keep the pen charged at all times and if you are forgetful like me you never have to worry about losing your pen. The keyboard also folds quite nicely under the screen during note taking and leaves the pen slot on the front so it is very easy to pick up and put down the pen when note taking or drawing. Totally recommend!

...If you want to utilize all the features available to you on your Surface Pro 9...(Sigh). Great keyboard and Pen, too bad there's not a "Neutral" selection for the Reviewer. Both of these units, individually or as a "package are a bit over-priced (a mere additional $300) in my opinion. That you have to buy them separately, as accessories to your new Surface Pro, is sure to delight no-one! Someone really screwed-up this time. Basically, we're now being "forced" into purchasing items that flesh-out the capabilities of the Surface Pro 9. Are they good...Heck yeah! Is it right that we're "forced" into this position? No, that's just greed on the part of MS. Shame on you MS, shame!

The Microsoft Surface Pen and Surface Pro Signature Keyboard are simple, elegant tools that work exactly the way you need them to. The Pen writes smoothly with almost no lag, making notes, signing documents, and sketching feel natural. The Signature Keyboard is lightweight, comfortable, and snaps into place instantly, perfect for switching between work and personal use. I love these items because they’re minimal, reliable, and make the Surface experience feel complete.

This is my second Surface Pro keyboard. I have the Surface Pro 4. I went this black this time because the grey, over time, shows palm marks. I'm assuming I won't have that issue with black. Works well. Keys have a good touch and pen works well.
