I have not used this aside from turning it on and looking through the eyepieces. I took two pictures through each eyepiece and I can see light through each one and the pictures show that but I have not used it to magnify anything. I purchased this from someone that was a smoker. I am not but there is a lingering order of smoke on it and that may dissipate with time and may dissipate before shipping it out, but upon receiving it it may still have the order of smoke on it. This is not new and show signs of use and age. Please use the pictures to help determine the condition of this item. I am selling this item as is. I will remove the top piece and the eyepieces which also slide off and wrap them separately and ship them with the microscope so as to protect them and reduce the size of the packaging.
