Perfect fit, secure pencil slot, great touchpad.
Color: Navy Blue
EXCELLENT Keyboard case. I tried several to find the right one. Tried a bluetooth keyboard by itself, but there wasn't the convenience of an "all in one". Tried another one that had a magnetic connection between the ipad and the keyboard, but the ipad was not as positionable as I needed it to be. This "folio-type" case is similar to what I use for all my other tablets and devices - slim, securely closing, perfectly fitting my 3rd gen ipad pro - AND the slot for the apple pencil is PERFECTION! The touchpad is a little stiffer than I like but then I realized I DON'T actually have to press it to use it - just a tap accomplishes the same thing. I rely on the touchpad for a lot and this case is just really exactly what I need.

good value and battery life
Color: Purple
Love this!! the keyboard has a good life on it and charges pretty fast. I at first didn't really like that it detaches, but being able to hold the keyboard in my lap and type on the screen while I sit on the sofa is actually pretty nice. the trackpad does have a bit of a learning curve, but gestures/hotkeys are all listed on the bottom so it's easy to check whenever necessary.
The material of the case itself also cleans really easy. I spilled a drink on it and it wiped right off. I feel like this is a pretty good value all things considered, especially when similar products at big box stores can eb a couple hudnred bucks.
The only downside is that the keyboard, while slim, does add a bit of bulk to the case. It's not a huge deal for me, but my boyfriend who also has an ipad did notice the difference immediately.

Works
Color: Light Gray
Heavy! It is a nice case and the keyboard works good. Turns off randomly, but not too annoying. This case is heavy though! It at least triples the weight of my iPad, which is opposite the reason I got an iPad Air. Too late to return, I just take the keyboard out, but it must be the magnets in the case that are so heavy.
