Works great, less expensive
I'm an avid user of the Dr. Mom otoscope. I'm a physician who has to do examine people's ear canal several times a month. The "gold standard" Welch Allen otoscope costs ten times as much. Sure, it's study, but the Dr. Mom brand does the trick for me. But it uses nonstandard (i.e., not Welch Allen) otoscope specula, hence this order.
Did the job. But broke 2 of the 5 needles with in the first 5 minutes of use. :(
