i bought these for elementary students to use  they are a very fun intro to a microscope and can be used in a variety of wayslike directly on objects or skin  the zoom is simple and allows practice to slowly adjust the zoom to get the focus correctly  the best part is the light lasts a while and is a very easy switch to another aa battery when it runs out unlike the other brand i purchased that takes a screwdriver and watch batteriesthese are really fun for inquisitive kids i recommend trying them on different fabrics leaves sliced fruit or veggies skin and on a strand of hairthey are a great value hold up well to frequent use and are fun
