When it's dark, it brings my opinion nothing when you turn the mobile on rotation because the changing light daruner not sufficient to illuminate the figures of Mobile in the dark. Therefore I turn night to be the Nachtkastl lamp so my little one can also watch the rotating Mobile falling asleep at night.
When we took the first time in operation, the Mobile, we were a little disappointed that the engine of the device is actually a bit noisy. But I must honestly say that we no longer hear the engine now. You get used to it and also this is also no longer be heard during the melodies - even if one switches on very quietly. The only problem of our Mobile is that it "creaks" every few minutes and the Mobile stops during rotation for approximately 2 seconds before it continues to rotate.
The sound sensor works perfectly - but I've already seen a couple of times that it turns on the automatic switching without the play of light, although we have always turned on the "Mobile Music Light mode" - which I find a bit strange. But otherwise I am very pleased with your mobile. The holder of the Mobile I find to be very safe. I always fingere a few minutes around until I have the part removed from the crib - it can not fall down by themselves certainly!
And the batteries we have since Christmas there and until now (end of January) at oftmaliger daily use not need to change - so actually last very long.
My daughter always sleeps quite quickly with this one Mobile, and even if it just these few "blemishes" has, which I have described, I do not regret the purchase. Therefore, I forgive won 4 points.
