I tried CVS (a chain drugstore) but they looked at me like they didn't know what an otoscope was! I don't need "great" but good would be nice I just want to check my son's ears. Can you believe he's 14, 5'9 and is on his third set of tubes? When he was three feet tall, they said "he'll grow out of it". At this rate, he'll need to be 6'4 before he "grows out of it"! Thanks!
