Just wondering if anyone had any experience with these. I know most people say not to buy an otoscope and opthalmoscope cause they will have them wherever you go. I kinda would like to have something cheap though just so I can practice on my own. I noticed that ADC sets are quite reasonable, but no one I talked to has any experience with them. I was a litte concerned cause the aren't a name I am familiar with like Welch Allyn. On the other hand, its really just a light and magnifier, right, so it doesn't seem like one brand should be that much higher quality than another. Also, do I understand correctly that these run on regular AA batteries? Thanks for the help.
