This Otoscope (or as my kids call it - the ear thingy) works great. Nice bright light really enables you to get a good look inside the ear and see the ear drum or to identify wax blockages. We used it right out of the package to take a look at my son's ears that have a habitual problem with wax blockages. We could easily see a large blockage in his left ear, which we proceeded to rinse out with multiple gently rinses...After each rinse we used the Ototscope to see how much we had left to clear out...Without the Otoscope we would not have been able to completely clear his ear. In the past we had to go to the Dr. to have this done. Doing it at home is way, way cheaper, AND more gentle than the Dr.
