Either one star or five, depending on

When the number of stars to be awarded, I am unsure. First bothered me that the German keyboard functioned American, but the device can not, I could at the smartphone (Nexus 5) beseitigen.Was but significantly interferes, the multiple character that triggers each keystroke. The sensitivity function (FN and comma or point) that was not to eliminate.

Then why not just a star? Because I bought the device used ("very good") and does not know whether it's because. The switching on and off, which recommends another reviewer, brought nothing. Had the device unfortunately send back.

If this unwanted effect would not, I would give it five stars because everything else works surprisingly well. The brightness can be adjusted within wide limits, the base needs to be by no means know. The key beep can be put quietly and silently. The Bluetooth connection to Smarty was seamless. I'll probably try it again with another device. A return is so simple from Amazon that you risk nothing.
