Not bad... unless you want to use it to check an eardrum
This could be useful to check the throat or to check for earWAX but I got it to check my son's ear for earaches and it just didn't work.  The magnifying glass is not strong enough to see the eardrum, and even with suggestions from my pediatrician I could barely make anything out (making it impossible to check for redness).  I returned the item because it just wouldn't do.  I'd suggest investing in something better and went with the Dr. Mom scope with the LED light.
