I've trying Magic Desk for the last few weeks as part of a testing program. It is a pretty smooth experience which helped me feel more productive in my day to day life. Easy to adjust thanks to gesture control, its light sensor is pretty intuitive. Recommend you guys take a look.
The Air 2 is light, compact, and comfortable to hold. Although it looks like an ordinary toothbrush, you will immediately notice the difference between Air 2 and traditional electric toothbrushes: there is no noise!
