So I'm super happy with the microscope. I gave it to my 8 year old nephew birthday and he went immediately on discovery. Everything works fine and for the money, there is a 5 star buy recommendation! The quality has my nephew also equal to the test posed. Because it fell from his hand on the stone tiles, the microscope! All have thought "That's it". But it has the impact without a small scar over! Absolutely Top !!!!!!!!!!!!!!!!!!!!
