I don't typically write reviews on products that I purchase from Amazon...but this one truly deserves it. First, the price was awesome ($14.78)!!! Second, it feels well built and is very comfortable in your hand (just the right weight). Third, the light output is amazing for such a tiny flashlight...and the blue color of the light is beautiful!! You can slip this in your pocket just like a pen so it's ready when needed. I am going to purchase a bunch more to keep in every room of the house when the elec goes out, and to put in the glove box of our cars. I had never heard of AAAA batteries before...in a silly way, they are cute! I have only had the pen for about 3 weeks now, so I can't report on the battery life, but for $15...well worth it even if the batteries didn't last that long.

Brought these as stocking stuffers for Christmas. Great little gadget. Small enought to stick in a briefcase or pocketbook. Light is very bright.

Recently I ran into someone in a second hand shop searching for Vaseline glass popular in the 1930's. A sure fired way to determine the authentic stuff is to shine a blue light on it. If the tell-tale bright green color reflects back, it's the real thing. I think it may also reveal cracks in glass which may not show up so readily. I wanted a reasonable, pen sized blue light and this one fills the bill perfectly.

These are the best pocket flashlights ever. Small enough to fit in a pocket unnoticed, but powerful enough to light your way out of anything. And the battery life is so long that in normal use, you will never get around to having to replace the batteries at all. My only complaint is that I have to keep buying more because my friends keep taking the ones I have with me.

The streamlight 65022 Stylus 3 Cell Flashlight is a great device using the blue LED light for the ideal visual tool to see in the operations of commercial ink jet printing machinery. This flashlight is small enough and powerful enough to get in and see any ink flows and any problems the printing equiptment may have. The blue LED lights make it possible to see the things one would never be able to see with a white or any other color LED light (as a black light shows). The size of this product is exceptionally convenient being the size of any average ink pen. It has been a great tool used in the printing industry to keep checks on ink jets fine pecision parts.
