On the whole this is a really good night light. One mode isn't listed here, which is an SOS mode which is fourth in the mode cycle. For photosensitive/epileptic people it could be problematic if cycling through the modes without being aware of it. The instructions are a little lacking, but it is easy to operate. A tap in the centre turns it on and subsequent taps cycle through modes until it is off. If you long hold the centre it will turn off and remember the last mode you had it in, including colour choice, when you turn it on again.
