The projection clock is very useful and really well done. You can wave your hand in front of it to turn it on/off. You can as well choose to have it automatically on for a few seconds when you wave your hand in front of it and automatically off after a few seconds. In oder to benefit from this feature, you have to use the electrical adaptor.

The clock has the backlight that can be turned on permanently (with electrical adaptor only) or disabled.

It's really easy to use and the user manual is well written.

Perfect to track the sleeping and feeding pattern of a newborn :)
