We bought this for my son when he was about 3 and a half months old. He LOVES it! I liked it better than the classic doorway jumper because there is no way for him to hit anything in it because it is suspended from the three poles instead of just the one bungee. We also liked that it was alot mor elike the traditional exercauser than the doorway jumper. It has toys the whole way around the tray and makes noise when he jumps. It has 3 height adjustments too so I know he will be able to use it for a long time.
The downside to this toys is thatthe sounds can be quite annoying after a while but that is usually the cause with any infant toy and at least this one can be turned off. Also, the seat can be removed to be washed but the "headrest" thing on the back of the seat takes a long time to dry.
Overall, I would highly recommend this toy to anyone who is looking for a safe place for baby to play while you get some things done!
