I was a bit skeptical because of the low price, but have let myself be influenced by the reviews. The microscope came yesterday on the birthday table my 7.jährigen daughter and both she and the rest of the family was thrilled. A really great device to introduce them to the world of microscopes. The device works without much preparation, both can not slide as also with used and shows remarkably good results for that price. Come definitely on my list of great, unusual and affordable gifts on the occasion of a birthday invitation. I will certainly give even among friends.
