Penlight with convenient pupil gauge on side. Replaceable battery. Made in USA.
Love the pen light, but I was always carrying an extra set of batteries with me. It kept getting turned on by accident in my bag. I would go to use it and the batteries would be dead. I ended up taking the batteries out when I left work?O then finally switched to another pen light.
This pen light is easy to use, has the pupil sizes on it and I love that it clicks on and off like a pen.
very nice for the price, convenient pupil gauge right on the light is great for immediate reference.
Like this product very much, gives an excellent view of the pupil size and it's reaction to light, far better than a regular penlight.
This was a good pen light initially. However, the pen light developed a poor connection at the top. This occurred after the 3rd battery change. I would not recommend, because I expected more life out of the light.
