## Customer Reviews

### ⭐⭐⭐ 







  
  
    It's functional, but has some issues.
  

*by A***L on Reviewed in the United States on February 27, 2013*

Works like explained. once you stand it up, it will not go all the way down again, as if it was bent a little. It will still close, but looks lopsided. The case that the phone clips into, slides onto the keyboard, and where that happens on the case is a little weak. Mine has cracked and broke.The backlight is nice, but it does not shut off automatically, have to turn on and off like a switch using a function key. takes about 7-8 sec to re-sync when it goes to sleep from inactivity.

### ⭐⭐ 







  
  
    Fair
  

*by C***L on Reviewed in the United States on October 26, 2013*

This keyboard doubles the weight of the phone.  The phone weighs 4.65 oz.  The keyboard weighs 4.65 oz.  At a whopping 9.3 oz  in weight this makes the phone cumbersome.  The phone no longer fits in any case.  The symbols on the keyboard are difficult to get it to.  The keyboard on the telephone does not disappear and remains on the screen.

### ⭐⭐⭐ 







  
  
    Functional, but not fully polished.
  

*by S***  on Reviewed in the United States on January 15, 2013*

This unit clearly had plenty of thought put into it; it includes just about all features you'd want, and is implemented solidly. There are just a few areas where it could use more polish.As a keyboard, it works well. Pairing is no problem, and it does just what a keyboard is supposed to do. The special keys (search, media pause, etc.) work as they should. It's not *quite* as seamless as a built-in keyboard - sliding out the keyboard doesn't put the phone in landscape mode automatically, for example - but that's hardly the keyboard's fault. It's worked well with the apps I've tried. Crtl-C and Ctrl-V and so forth work to cut and paste as you'd like.It adds *considerable* bulk to a thin phone, but the fact that the rubberized 'case' portion is detachable helps make up for that. You can adjust the angle of the phone through almost 90 degrees, but past a certain point the phone starts to block the top row of keys. I've been able to use the camera without adjusting the phone angle, just sliding the keyboard out.There are a few cons. The keyboard layout could be improved by the addition of a shift key on the right side; getting a capital 'A' or 'S', or especially 'Z', is a mite awkward. I'm still getting used to the narrowness of the space bar. Finally, the unit I received had a minor manufacturing defect - the "Delete" key is mislabeled as a second "P" key. This is only cosmetic and doesn't disturb me particularly.
