We got this for my daughter's first christmas when she was 6 months old. I put it together in less than 10 minutes. It is very sturdy and made of colourful plastic.
It has a detachable front with a carry handle that my daughter found very entertaining and still does 2 years later. Its educational too. It has piano keys at the front which can either play music or say the abc.
Very useful for parents is that theres a volume switch with two volume levels and you can also switch it off when it gets too much for you.
The battery life is pretty good too as in the two years we've had it we've only had to change the batteries twice and my daughter uses it quite often.
It has helped my daughter with learning to walk too and she started cruising at 10 months.
It is worth it if you pay full price for it though shopping around for a bargain is always the best.
