  • 5 out of 5 The clip on this light makes it the greatest micro light there is. Clip it in your pocket like normal or you can clip it to the bill of your hat. Genius! Exceptionally bright for a a AAA flashlight. Will buy more.

  • 5 out of 5 This a great little light. it is very bright for only using 1 AAA battery. I used mine while working in a Jail. It has been dropped and kicked many times and still works like new. I left it in my shirt pocket and it was washed many times. All of this in the last 2 years and it still works like new. This is by far my most favorite light that I have, I even like it better than all my Mag lights, one of them being a LED XL50. My wife and kids also like using it. I am going to have to buy them there own so they will stop taking mine. If you are looking for a good and durable little light, you will not go wrong buying one of these.

  • 5 out of 5 I keep looking for a better everyday flashlight to carry. After years of searching I have found nothing better then this little beauty. It takes a beating, and still performs. My biggest problem is people borrowing it and not returning. So I have to always ask for my light back. There are brighter, more tactical, more bells and whistles, but if you want a no nonsense EDC light....look no further.

  • 5 out of 5 I have a number of different Flashlights and this one is my favorite for several reasons. It is small enough to take with you everywhere you go, super bright for 1 AAA battery, durable, has handy clip that also works with a hat for hands free which is a great feature, tap for a quick light. They covered it all! Makes a great gift.

  • 5 out of 5 I have this with me almost all the time. Small enough for everyday carry. Mostly carried in my pocket, but sometimes on the included lanyard. Like them so much I've bought about 12 of them. Everyone in my immediate family has one, and several have been given the ProTac 2L in addition. A lot of light from a small item with decent battery life. A very practical piece at a great price.

  • Nice and compact, very bright for the size.

  • 5 out of 5 Because it's So small you forget it's there it is always there; provided I don't forget to change it from one outfit to another when I change my clothes. Bright enough to take the place of a much bigger flash light. I have worked under a house with this light. A lithium AAA fills it and one lasted me a month on the job as a service plumber. Even let a co-worker use it to change a filter in a under a house. The clip allows it to ride on the bill of a ball cap so both hands are free. The three I just purchased were of other people that were amazed at its' versatility. If I had been a little more flush I would have ordered another for me. I purchased the nano instead and was pleased with it. I

  • 5 out of 5 This is may second purchase of this particular light. My little sister was home on leave from the Marines and I ended up giving here my light. I carriied it with me everyday and when I went to reolace it at my local Gander Mountian where I made my original purchase but they did not have any. I ended up on Tacticalgear.com and was able to purchase 2 for about what I would have paid for the 1 at G.M.

Nothing bad to say about it. My wife and I bought 10 from Tactical Gear to give as Christmas gifts this year. Love em.
