I bought 2 of these. It worked great for the first couple shifts, but after less than a week of light use I took it out to use it and found that it didn't work. Maybe it got turned on by accident. I started replaced it with the second one and had the same result. After that I started buying cheaper penlights and one of the cheaper ones has lasted me for almost a year.

The product as it arrived was nice. It had a good beam and would have been useful, had it lasted. I assume it must have accidentally gotten turned on at some point in transit, because it was burned out by the time I worked my next shift. I replaced the batteries, and it is still not functioning. I guess the LED burned out. In any case, it was a good price, but with shipping and handling, I kind of just threw away money on this product.

Our clinic ordered 2 pen lights, both pen lights did not work properly. One did not turn on and did not close properly, the second penlight only turns on after several attempts.

These are perfect lights for checking pupils. They are not as obnoxiously bright at an LED so they don't hurt my patient's eyes. They work as described. Delivery was quick. I like mine so well I purchased one for everyone in my office.

The colors and that it is metal not plastic. As noted on cons; really easy to be turned on in a case or bag. Was found with dead batteries after transport in a briefcase.

Easy to use!
