My 11 year old daughter asked for this. She is not really a science type gal, so I am jumping at chance to give her something that might pique her interest in an educational type way. I did purchase this for her for Christmas. I don't know that it will hold her interest for a long time, that is my only concern, but I'm keeping my fingers crossed.
My 11-year old received this for her birthday in November. Everyone at the party liked it. They examined skin, salt, carpet, hair, etc. and finally got a bug. Several of the kids at the party requested it for Christmas.
My child does not use it often, but when friends come over they want to use it and my child it still interested. It is all about what you are examining, so give them something good to look at.
My 8-year old received this for an early Christmas gift. Once it was hooked up and focused, he and his 7-year old sister ran around finding for things to look at. My husband was helping to find things and ended up monopolizing the thing for twenty minutes looking at a dollar bill. So -I'd say it's great for "big kids" too!
My 10 year old (almost 11) son saw this at Costco and told me he really wants it. I just bought it tonight and I think he will get a big kick out of it. It was the same price as Amazon but includes a stand.
