Query: Poor Craftsmanship

This microscope is poorly constructed. I purchased it for my daughter to use for a school project. Each of the lens were of poor quality, making it almost impossible to focus. The biggest problem was the microscope came without instructions of any kind, not even a note informing the consumer that there is a hidden compartment underneath the base for a battery. I would not recommend this product not even for a elementary school project.
