The Dream Big Bear Mobile is undoubtedly suited to calm and fall asleep for babies. One may choose to operate with or without light and the rotating dream bears enjoy safe tyke heart under 5 different melodies / sounds. Absolute drawback: The incredible battery consumption, the manufacturer would have better equipped the mobile with one power supply. We have the part now 3 months in operation and fewer than 4 batteries already sets (4 pieces of the thickest and most expensive) is consumed, although the mobile is actually operated only at night to sleep. At the same time we bought rechargeable batteries, but they are already sucked dry again after one and a half days. In addition, change the batteries is an ordeal. The entire Mobile needs to be removed completely each time, four screws must be loosened with a screwdriver and a cover to be removed. If the batteries are only weaker, the unit offers the craziest malfunctions such as lyres, squeak and squawk the music off / on button can no longer be operated, light is no longer on or off no longer. Conclusion: The money that you spend for the device, you will again have to forking out for batteries in the period for which the mobile is designed (aged up to 5 months!). Every other music Mobile without completely superfluous remote control and the light frills to the baby anyway hardly perceives is, fulfill the same function and is safe electricity and money saving.
