$10. I'm sure it will be quality. If you want a laugh, read some of the 5-star reviews. I always think it's funny that these chinese companies don't just hire a couple of translators rather than just using babelfish...
(BTW - just to be clear: I have this case. It's one of the several that I tried before settling on the logitech for android keyboard. I still have it because it came directly from China and I couldn't reasonably return it. Don't be fooled; It's absolute garbage. Even if it was moderately good quality (it's not) the keys are tiny and either don't work or they stick; the case comes apart quickly, and there's nothing to stop the tablet from coming out the sides. Really. This is pure garbage. If you can you should cancel).
I ordered the Logitech Android Bluetooth Keyboard. I got it off of ebay for around $30 shipped (refurb). I'm sort of dubious that a keyboard that could fit into a case would also be a keyboard that would benefit typing over and above an onscreen keyboard.
Read the reviews on that Amazon page, they're pretty great. I think the logitech keyboard is small enough to be always in my bag, but big enough to give me a significant jump in my ability to type things if/when I'm in a note taking station.
