We had one of these for our first son. We loved that it was both a swing and a bouncy chair in one, but it had problems.
It clicked CONSTANTLY while swinging. The motor wasn't strong enough to consistently swing the chair + a newborn, so the chair would slow down, slow down, slow down... stop, then slowly start up again. Then the whole process started again.
Also, the music and sounds are really poor quality, to the point of being obnoxious. We didn't use them.
Just so I'm not totally negative, here's what I liked:
1. Two "gear" items in one.
2. The angle of the chair in the swing is adjustable, so you could have your baby lying all the way back or sitting all the way up.
3. Once our baby had more head control, the bouncy seat was FABULOUS. We'd sit him in it and take him from room to room while doing other things. He seemed to think it was pretty comfortable, and I could tell he liked sitting up so he could watch what we were doing. And if he fell asleep, it was easy to lift the whole chair and transport him to a quiet spot.
I'm pregnant again and we still have the swing/chair, but we're registering for a different one (and focusing on picking one with good reviews for the motor and quiet operation).
