      This little flashlight is awesome!!

      Overall: 5 out of 5

      Love this little flashlight! Its small enough to carry in your pocket at all times. Bright for its size. Can clip onto a variety of objects with the double direction pocket clip. Its not big or heavy so you can even clip it to the side of your glasses to provide hands free light right where you need it. I have been using this for 7-8 months and have never had any negative issues with it. When the battery was drained it shut down, a couple minutes later it worked again for short bursts allowing me to finish what I was working on before having to find a replacement battery. If you like having a flashlight handy at all times, this little light will not disappoint. I like others will be ordering more to give away as very useful presents. Well done Microstream!

      It provides very good light. With advancing years, my eyes, like those of many other elderly people, are failing. It is a terrific help when I need it. I keep it in a pen holder on my coffee table and it is readily at hand without creating an obstruction or clutter.

      Bets Overall Flashlight Ever

      Overall: 5 out of 5

      I have a weakness for flashlights, I've tried a lot of them over the years (I'm 53).
      I have been using this little wonder for over a year now (my 4th, I lost one, and gave a couple away)
      I also ordered 6 to give for Christmas. That's how much I love it!
      It is small (pocket size, lite, one commonly available AAA battery) Very bright, can be held in mouth comfortably! or clipped to hat brim. Very sturdy! one thing to keep in mind, it is digital, so when the battery gets weak it won't get dim it just turns off, that your signal to put in a new battery, not beat the thing to death! (keep a spare battery handy)

      OUTSTANDING pocket size flashlight!

      Overall: 5 out of 5

      I carry my Microstream with me in my pocket all day - every day. i use it many times each day for a wide variety of things such as servicing and installing equipment, inspections, reading menus, searching for small things that fall on the floor and hide in unexpected places, and even for scanning the back yard for skunks when I take the dog out at night. A common alkaline AAA battery seems to last forever. It has even survived several trips through the washing machine without any problems at all. The light is surprisingly bright for being so small. It is very well made so it is rugged yet light and small enough that it can be carried with you as easily as a ballpoint pen (only shorter!), and that makes it something that gets used so frequently because it so readily available to you. I have several Microstream lights and give them as gifts to friends, family and co-workers of both sexes! I learned about the Microstream from a good friend and Firearms training instructor, Randy Smith, may he Rest in Peace, that always carried one with him so I think of him and thank him whenever I give one of tell someone about them.
