A cellular had to send me a replacement since the first shipment never reached me. Upon set up the space key would not work. After some time working with it I switched to portrait mode and the space key worked. i have not gone back to landscape mode to do another test. I really like the special keys on the keyboard such as the one that takes you out of the app you are in or takes to to the home screen. Those keys make it very useful. Had the space key worked I would have being it five stars.
