WelchAllyn Pocket LED Fiber-Optic Otoscope with AA Battery Handle - Professional Portable Ear Scope for Home & Clinical Use - Perfect for Doctors, Nurses, and Parents Checking Ear Health

I have one of these and really like it. It is lightweight and lights up well. I have to change the batteries every 2 to 3 weeks, which is not bad. I bought another one for my PA. The only complaint I have is that the clear plastic 'lens' tab broke on mine, so it is not secure; however it has not interfered with me using it.
