Really great, I still take the app has an external one proposed by philipps order to create scenarios ($ 5 more ...) with a change of pace, color, and variations .. Three faults to my taste, the white brightness too low to be enjoyable to read at night, and the fact of using the app or tap (a buy in addition) to illuminate the night of the coup is impractical .. and of course the price .. After I knew all these disadvantages and I do not regret my purchase, it's been two lights moods, what is more we can do lots of scenarios or choose an automatic change via sound ambient .. Project and therefore useless geek completely imperative to have;)
