Weaknesses: Batteries - 3 AA and 1 D! Vibration can be rattly. The toy bar is just out of her reach still at 3 months old.
Overall: Really good for the money. There are cheaper/more expensive chairs on the market, but for £44 this one came in on budget. My little one seems to like it in there. She can fall asleep whilst on vibration mode and can be sitting more upright to look around and play. She likes the music and lights....especially the 'DIY'mode. (When she kicks, it lights up and plays music. Just wish the toy bar was closer to her..... Oh, and that it wasn't blue.
