Query: Good otoscope, terrible opthalamscope.

I am in my first year of medical school and I bought this for use in training and rounds. Do not buy this if you actually want to see any part of the eye. I could barely see the red reflex and once I followed it, got a huge reflection of the LED light right back at me in a very small viewing lens. Visualization of the fundus is impossible.The otoscope is just fine.You get what you pay for!
