My son loves this swing. He likes to look at the little bears (we even added a few other toys for him to look at) and it lulls him to sleep. It features a vibration (which you can turn on and off and adjust the level) and music (classical music and nature sounds). Versatility It isn't super versatile-- it basically rocks back and forth. But, little ones love the soothing rocking and it seems to be working great. My son didn't like it as a preemie newborn, but he is not 9 weeks (adjusted age) and he LOVES it! Durability We have moved it around and it seems to be very portable and durable. It is big and slightly bulky BUT, durable! Ease of Use The buttons are clearly marked and very easy to push. There are only a few buttons, one knob for swing speed, and a control for the vibration. Everyone will find it easy to use! Safety I feel that my son is extremely safe in this swing. I can leave him in a room by himself and know he is fine... Features It has an adjustable vibration feature, nature sounds, classical music and you can adjust the speed of the swinging. The features are perfect- and I feel a lot more is offered in this swing than in other swings.
