Query: Great item and a great value!!

My 7-year old LOVES this microscope. I never dreamed he would be so thrilled with it. It's durable and the lights work great. I did not expect it to be so well built at this price. And, it a good thing, because he carries it from room to room. I bought him some prepared slides too, which he has really enjoyed. The magnification and clarity of the lenses is also great on this scope. All around...a great deal!!
