simple processing of plastic, but good function - writing experience quite enjoyable.

For so an absolute cheap thing I find the keyboard really very good. Then it writes better than twice as expensive brand gizmos. The design is reminiscent of the clear of a known manufacturer, the processing is not just ok.
The connection to the smartphone went smoothly.
The batteries supplied, brand Penesamig, I'll dispose of unused because I have no desire for another verätztes device. I prefer to use alkaline batteries from a reputable manufacturer or a supermarket's own brand.
