The keyboard itself is OK. The keys aren't that quiet though and require a little more push than what i'm accustomed to considering the keys are flat, but it's OK. Typical additional row of iOS-specific keys. The only button I wish it had was one for Spotlight, but not that many keyboards have a keyboard like that.
It has some good viewing angles, but adjusting the angle can be a little cumbersome. I say that for a few reasons. One being that you CANNOT just open it up and use it like you would a laptop (even with all those hinges). You could...but if you tilt it past a 90 degree angle, it will likely tip over the entire case because the iPad makes it top heavy. Pretty much every time you use it, it requires you to pull the latch on the back edge of the keyboard, then pull the grey base of the stand for the iPad out a little bit. This will let you prop the iPad up at the better and more secure viewing angles.
Now one of the main draws of this keyboard, for me, was that you could use the stand alone. Honestly, it's not all that. It's main problem is that the hinges are not strong enough to support the iPad as if it were "floating" (think of how an iMac is supported by its base stand) and it will tilt downwards. This also occurs when the stand is docked into the keyboard. If you use it more as a support and the iPad's bottom is touching the table, it works fine. It DOES rotate, but it feels shaky.
The build quality is OK. Kinda plasticky. The backshell of the iPad is pretty light if used by itself. However, it looks/feels plasticky and it does not offer any lip protection. You get decent access to all the ports, no problem there.
Overall, I think it's just OK. For $55 bucks I think its pretty good, especially compared to some other options.
Is it a keeper, though? Honestly, I'm thinking of returning it for a more simple folio style case or something like the Logitech keyboard cover. I don't like the shell that much. The stand was also pretty disappointing. Dealing with the latches when you briefly want to use the iPad then put it away is cumbersome. Also, I don't like how the screen comes in contact with the keyboard when shut. It just doesn't feel safe for the screen, like there's some pressure on the screen. Also, I wish it was quieter.
I'd give it 3/5 stars. There's a lot of nice features and it works OK, but I don't have a lot of good things to say about it honestly. I might change my mind after some use, but we'll see.
