Have bestowed this Stereomicroscope 8th birthday to my nephew. The batteries I had previously inserted but he has the rest - chop, chop - all alone hingekriegt and understood. Has equal to 2 have ordered preparations (Scorpion and stag beetle) considered it, then leaves, sugar, salt, pepper and a few herbs, a chestnut and everything so came in our way. Generated widespread enthusiasm and on weekends, he had to take to his dad it right. It's super handy, yet robust and enables good viewing of coarser / larger objects. I myself am a scientist and in the company, we also have a microscope from Bresser (an inverted microscope) and the products are really good for the price. All in all, very satisfied.
