The Display from Avinusa.com is outstanding and works perfectly. I can highly recommend this product. The big Touchdisplay makes it easy to work with it.
I have also tested two other Boxes but without success.
The worst box came from Skandinav.de and did not work. The Support is horrible, and most of the time you get only a “received message” but no answer. They are incompetent, so I can not recommend the Products from this Company.
