Well, we liked the fact that the colours are neutral and that the music is acceptable unlike many other exercisers. Our baby uses it 3 times a day for about 10 minutes each time. She really enjoys every piece of it... when she can use all the pieces! She can easily take off the little grey rod with the leaves/cat and it is impossible to put back in place, it will just get off every time now. She can also take off the bunny with the electronic components. She overall structure is also very flimsy, not good for developing babies testing their abilities! So on 6 holes, 3 of them are now empty, making it not that interesting to use. Also, the seat doesn't rotate that easily compared to other jumpers we used, it gets frustrating for our (strong) baby. All of this make it very dangerous, I wouldn't recommend it.
