This is the second time we bought the microscope. The first time we informed us at a high school teacher because what is suitable for NEN 6-year-old boy. The inquired of a colleague of Biology and this meant that the increase in the microscope is more than enough for 6-year-old children because their eyes not all absorb as we adults. That sounded plausible enough for us to try our luck at and even if the microscope will cost 50 euros, we have found that we are having some extra money investing mostly driven better than if we only pay attention to the price again. The microscope was delivered as described and also equal to unpacked and tested. Batteries pure and light switched on. Works and one can well recognize the place which is illuminated. The insert (Black / White) turned over and also found that this worked with no problems. Then unpacked NEN stone and placed under the sight glass but what is it? I see nothing !!!! We were already disappointed bitterlichs because we had so it it pleased our son bestow birthday. Again read the manual and found that we seem to have done everything right? A few days later I tried my luck and found out the mistake. We must hang up his eyes to the Sichtgläßer not directly but keep minimum distance between eye and sight glass !!! That works just fine and can be seen on the stone really every channel, every fiber, every color change .... We're thrilled. Our son, we have also explained and so he gets it after initial practice with 6 years back. Of course, he also has the same boy Typically all examines possible. In a dead bee wings as (the madness times under such enlargement !!! consider), or Young Typical :-) fingernails! Yes, the increases already insanely big and it's fun to look at things like that. So I can recommend this 50 Euro well which are well laid out in this microscope !!!!! My mother was also excited and recommended it to a friend as a Christmas gift for her granddaughter. These are also excited and so I can now write this review !!! Have fun with it !!!
