“For a student or home-lab microscope, especially in a high school context, the N400M-XY is a very good value offering robust build and better-than-basic features (mechanical stage, abbe condenser, LED illumination). If your needs are within the realm of observing prepared slides, pond water, plant cells, etc, it should serve quite well.”
“400 times is Enough to see red cells. My 7 years old learnt how to use it within 5 mins. The product is solid, powered by cable. Beautifully designed and I used it once a week too. Recommended.”
