At first glance, the keypad is a useful addition. Disillusionment after unpacking: - Keys and surface are plastic (instead of aluminum). - Underbody and battery compartment are so thin constructed that they will not last. - The distance between the main keyboard and keypad buttons is too narrow designed. - Connectivity via Bluetooth is deficient with regular interruptions. - The keypad will be recognized as a separate keyboard, that is customary in a single keyboard shortcuts do not work.
All in all, too expensive and unnecessary in this form product.
