this "thing" is still smaller than you had thought and we think inevitably that it can not function. But in fact do it properly! I thought it would Keymate ordered because of the size and because I have this ubiquitous "Smartphonegewische" and the illuminated faces of our Head-down generation getting sick. I want to call and sms write (and do not waste my time with Peanuts) and that's really good. I have real Wurstfinger but I scurry elfin via the keyboard, it's a pleasure and my wife and children stare blankly (the thing is the size of my thumb ... Okay now that was a lie ...). So I am (which now offended rotted away in the drawer) prescribed much more frequently at my touch screen phone. The display is super read, the sound is Ok. The mp3 player I use infrequently, have no desire to constantly reload, but will sound wonderful. Only the title search is a Herculean task, because only 1 title may be displayed, but if you know your way, it is not a problem. The second battery supplied I lift only at times, great thing is to show at some point, why the manufacturer a second mitliefert !? So it's a Funteil which however proved itself in everyday life. One has to stop and want. And the eyes of others are really terrific goofy. If the Keymate had a camera, I would nevertheless not take pictures because that simply does not brauchts. Is just a phone, right?
