We bought this for a boy (age 10 1/2).  He found it interesting for a while, but grew tired of it quickly.  If you have a child who is really into tinkering with electronics, etc., then this might be a good choice.  Otherwise, it might become boring too quickly.  Once the user gets a feel for how each of the included circuits, resistors, etc. work, then there's not much left.

As a parent, I will add that the guidebook which comes with this kit is very informative.  It provides a lot of easy-to-understand introductory information on circuits and similar topics.  My son seemed interested while we did a few of the lessons and projects together during some "father/son" time.  I think this type of information is good for developing brains, since it gives children a brand new topic to analyze and absorb; it also gives them a basic understanding our our "electrical world".

In summary, I have mixed feelings.  If you have a child who shows a liking or interest in this type of toy (assembling, testing, doing small projects, taking apart his/her current electronics toys to see how they work, etc.), then this might be a good choice.  But, I cannot pound the table and say this is a "great" toy.  It's a "good" toy for the right child.  If you think your child might be the "right" child, then I encourage you to give it a try!
