Negative points:
- The keys are not all reactive and fast tape may cause letters breaks. For my part, many keys and letters do not respond (to the out of the box). It is necessary to turn the keyboard off, on average every 10 minutes to recover all keys response
- No indication of charging rate of the keyboard, while the percentage with loads of tips are given in the online manual ... (??)
- No manual is provided in the package: obligation to go online on the Kensington website to read
