Bought this for my 11 year old niece. She loves it. Wanders a round with it inspecting the garden. Great buy.
This little nick nack is perfect for any rockhounder that wants to see microcrystaline structures. It's lightweight but doesn't feel particularly cheap, small but fit's in the hand well. Overall superb doodad
Brilliant microscope and excellent service
Kids love it…great to encourage outside adventures
