the kit is very educative and nice however:
1. each experiment si very short so it's not really 120 experiments it's more in the direction of 60-70 after u take like 4-5 small experiments sometimes and squash them into one big normal experiment.
2. it's not so durable and the test tubes are very thin and breakable, even for 10 years old.
3. they a bit cheapskate on materials and their amount is just right for the experiments in the notebook, but if u want to explore a bit with your kid beyond it it will not suffice.
Bought for my grandson aged 9. Has proved to be great fun yet educational too. Even mum and dad have enjoyed the experiments which only needed minimal adult input. Great present I've been told!
