Question about Punkt. MP02

I use the dot. I use MP02 in parallel with the same phone number as the Sony Xperia IV when I don't want to lug it around. The Punkt. MP2 fulfils my expectations, but it has certain peculiarities: The personal configuration via buttons is not very easy and takes some getting used to, the battery seems to have little capacity (frequent charging like a smartphone) and I had to enter my contacts by hand using the keypad because I couldn't manage an import. Otherwise, the device is excellently made and makes a solid impression. It is small, stylish and fits in any jacket pocket. With Bluetooth, it automatically connects to the hands-free system in my Mini Clubman JCW.
