This is an excellent kit and to categorise it as a 'toy' is wrong in all senses of the word. My 8 year old loves it and his friends are amazed. It has just had one component fail (because he was messing about and managed to overload the circuit), I emailed the company and they have sent me a replacement part FoC! There are endless circuits to make which means that there is no need to experiment until you know what you are doing and it is also great fun to do - especially the flying disc, the radios, bedroom intruder detection alarm and the morse code machine to name but a few. It is not cheap, but for value for money I would give it 10/10.
