Disposable Pupil Gauge Penlight
Product Review (submitted on May 11, 2012):
It's a basic penlight that you see on every ambulance whether it's a fire department or a private company. It's disposable so you can't swap out the batteries so I wouldn't use it for school. They do seem to last a really long time. I've had mine since I was in EMT school about four years ago.
The pupil gauge is also helpful when you're starting out.
I have had issues where the clip was pressed down so the light came on and wore the batteries down. Then sometimes the light wouldn't turn on no matter what I did, but then ten minutes later it would work fine. Sometimes smacking it really hard would work too. Usually the next penlight would work fine out of the pack though (I think this is just a single penlight).
If I were to buy one for school, I would get one that I can replace the batteries and is slightly more sturdier though.
