The parcel went without tracking, which is very inconvenient. We weren't waiting anymore. However, the miracle was accomplished. Packed is rather weak, but the whole came. Powered by three small batteries. Inserted very hard. But they already mentioned it here. The device itself is wonderful. Colors change, motion sensor works. Children are delighted! I recommend to buy.
It works, the battery compartment is crooked, barely enter, as well as one battery is very good while trying to shove. The rest is quite normal apparatus. Keep in mind in light and day does not work. The motion sensor is triggered only in the dark. It burns after working for 30-40 seconds. Hung olin in the hallway of poi vhrd, the other in the toilet. Very convenient.
