Very overpriced for what is essentially a slab of hard plastic with some raised edges, and some rubber underneath.
The presentation in the box is nice and elegant, but it still doesn't justify the price.
INSTALLATION
Installation is very tricky, particularly for the trackpad.
One needs to press very hard on the corners of the device for them to click into place. It's concerning considering how expensive the Apple trackpad is.
I understand this is to secure the devices, in case you use them on you lap, but if you are only using on a desk, I recommend to smooth the corner hooks with a small iron file.
ERGONOMICS / FUNCTIONALITY
The close positioning of keyboard and trackpad might take some getting used to.
Because they are so close, it happens especially at the beginning that you hit the trackpad instead of the rightmost keys, particularly the arrow/cursor keys, because the perception of the width changes. Also naturally the keyboard will be a few millimeters higher, which is noticeable.
If you are happy with that, than it delivers: it provides a tidier layout on your desk, and guarantees that the relative position of the trackpad remains constant, so you don't have to search for it.
Once the devices are installed, they are firmly in place, there is no wiggling, sinking or any other sort of play.
For left handed people: the position of keyboard and trackpad cannot be inverted, the trackpad can only be placed on the right hand side. If you use it with a stylus and you are left handed, this is not for you.
CONCLUSION
There isn't a great deal of choice on the market, so by all means give it a try, but don't get your hopes too high just yet.
