Query: Exceptional microscope & NOT just a toy.

This is really an excellent microscope. I bought this for our 12 year old daughter after reading many reviews, comparing, and shopping around for months. I didn't want to get a cheap toy that would go in the back of the closet and never get used. This model is so easy to use. It's made of metal so it's heavy and really sturdy. We haven't hooked up the photo/video link to our computer yet, but the view finder is extremely easy to use and see through - even for our younger daughter. They both are constantly finding new things to view. I wish it came with more slides, but I just purchased them by themselves from another Amazon vendor. I bought the set of 25 pre-prepared slides too and they are very worth the money. Honestly, this was the best model, with the best reviews for the most reasonable price I've found anywhere. This is a GREAT BUY!
