The telescope is not viewable, hence you will not be able to see the little cards through the telescope. I think for the price they could have put in a real lens. It operates like a real telescope, but it is disappointing that it not viewable. What is the point of have cards if the lens does not work.
Other than that disappointment, the other products are of great value. the apron has velcro closures, and the science book is a real book with interesting facts in it. The test tubes give the illusion of real liquid when they are turned up-side-down. For play time the set is valuable and is a wonderful addition of one's collection.
