Bad quality on axis
Reviewed By:
Thom (Montgomery Village, Maryland)
I purchased this set to give a demo to my daughter's second grade class. Unfortunately, there was a defect in the center ~7 mm of each lens, rendering them useless. The defect appeared as a serious figure error, but was more likely caused by an inhomogeneity in the index of the material. You cannot hold two together to make a telescope or anything like that.
