First off, the fit and finish of this keyboard case is very impressive. It has a nice sleek carbon fiber look and magnetically aligns with my iPad Pro 13". The whole thing gives a sense of precision engineering and craftsmanship.
There is enough stiffness in the hinge to hold its position while being easy to adjust.
The key travel and overall feel of the keyboard is very nice. It does not feel like a cheap keyboard, and I suspect it will last for many years. The backlighting is nice and even and cycles through 12 different colors. There are several function keys to control the various settings, and they are above the top row of number keys. They work with the actions represented by the symbols without additionally selecting the fn key. There is no alternate F1, F2, F3, etc. designation on these keys, but I presume they will work as such keys when using in tandem with the fn key, but I don't know of any iPad apps that use those to verify this. Overall, though, it doesn't feel cramped, and there is no hesitation or lag when typing.
The trackpad area is a bit small but very responsive to gestures. It has more width than height, which takes a little adjustment. Being left-handed, I became accustomed to the superiority of Apple trackpads years ago and have low tolerance to the inferior ones I find on almost every other laptop. I would compare this trackpad to be a close second to an Apple trackpad and far better than any other trackpad I've ever used. Panning around and zooming in/out in Apple Maps is smooth and effortless with this trackpad, and using 3 finger swipes to get out of apps or two-finger swipes to navigate through different pages of apps feels very natural.
The case comes with a small manual that clearly explains the keyboard and trackpad options, including function key usage, gestures, and some settings in iPadOS to modify behavior. I found the manual concise and very easy to understand.
It's all not perfect, though.
The case connects via Bluetooth and doesn't offer pass-through charging, so you need a separate charging device or cable for it. I have a PD charging cable that shows wattage level, and I can see it charging at around 1W. I haven't run the battery down yet, so I don't have an idea of how long the charge lasts or how long it takes to charge fully. Luckily, my iPad Pro is extremely power-efficient and can last a few days on a single charge, so this isn't a big deal.
There is a limit to the hinge openings. The main hinge opens to almost (but not quite) 90 degrees max, and then the cantilevered hinge opens to around 45 degrees or so max. I don't own an Apple model to compare it to, but based on my demoing at a store, this seems to be very similar. Still, I would've liked for it to open wider, as a personal preference.
The trackpad has physical clicking and does not offer haptic feedback. So, clicking feels solid, but after using a haptic-enabled trackpad, I found myself missing those little haptic features and having to get used to the excessive downward motion of the trackpad to physically click.
The flap that the Apple Pencil fits into is a little awkward. It does magnetically secure to the back when the case is open, but I found a couple of times it didn't fully latch with the magnets and hung in the air behind the iPad. After a few tries, I got a feel for how to maneuver the flap so that it stays secured. The Apple Pencil can attach to the side of the iPad for charging while in the flap, which is nice, but you will have to adjust it to where the magnets are aligned properly.
In comparison to the Apple MK model for my iPad, I would've preferred to have a taller trackpad and a shorter row of function keys like the Apple one, but this is a little over 1/3 the price. And for that price, it's a winner.
