Once delivered to the microscope: The processing of the microscope is really okay. To focus the table is adjustable in height, the table does not wobble and is as it seems, including the leadership made entirely of metal (aluminum). The turning handles (plastic) for height adjustment of the table have a kind of slip clutch that protects against overload. The LED for transmitted light illumination could be a bit brighter for my taste, especially concerning. Higher magnifications, with slightly thicker not as good see-through objects, this could be a disadvantage at the latest. The achievable focus when focus is very good in my opinion. Tentatively I once mikrokospiert my hair and lo and behold, there was even a structure of hair as well as it seemed, the surface can be seen (with me with tears!?). However, an annoying bug seems to be undermined Amazon here. The microscope shown does not correspond to the item description. Pictured is a Bresser microscope that in addition to the transmitted illumination also has a reflected light illumination and even left at the foot of a regulator to dim the LED (probably would be in this microscope, the LED also brighter). The product description from Amazon the picture but unfortunately was right and completely wrong and how I had to find today on receipt of goods .. From the imaged microscope from Bresser but I expect more opportunities in the long term and this is also getting low. Therefore, I will return the microscope only now received again. Because of the misleading representation error (wrong picture) Amazon there is a point deduction. Addendum: The figure has been corrected by Amazon. The item is now displayed correctly! (Due to the non-dimmable and but may be weak transmitted light illumination, it remains at a point deduction).
