Nice for the price,
This review is from: Afunta(tm) 8" Tablet Stand with USB Keyboard - Black Faux Leather Carrying Case-with Free Micro USB OTG Cable and Mini USB OTG Cable
I actually purchased mine from eBay for 2.99 and free postage too.
I liked it for the price so I bought 2 just in case these fall to pieces after a few months.
They look good and are well made but be careful when and if you carry your tablet about in it as my tablet slid out but I was lucky it didn't damage it.
Also make sure your tablet is compatible for USB connection as not all are.
You can check in settings and go to storage and scroll down to see if you have USB connectivity. You might have to check the little box there to be able to use it.
All in all these are a well made case especially from eBay for 2.99 with free postage. For the price this one is I have actually seen Bluetooth keyboard cases.
