  • Best pocket light for me.
I may keep losing them, but there's a reason I keep buying this exact same light every time. These things are tough, bright, the battery lasts a long time, and they fit anywhere that you need them to (sometimes to my butter-finger's detriment.) I keep this on my person nearly at all times. I've bathed them in engine oil and dropped them in coolant and hosed them with brake clean to get stuff off and none of it affects the light. These lights are my favorite! ... show more

  • Best flashlight ever!
Don't be fooled by the size of this pen light. This is made by Streamlight and its bright. As a maintenance technician, I heavily relied on my flashlight. This USB rechargeable flashlight fits great in any pocket. I trained many new employees and set them up with new tools and this flashlight was in every setup! ... show more

  • Perfect!
Really enjoy these lights, nice and bright, rechargeable and size. Use it all the time, bought this one because I thought I had lost my other one I had for years. My wife likes it also!

  • Good buy
Very good overall. Only thing I don’t like is the micro USB charging. Besides that, it’s plenty bright and very durable for a pocket light. I’ve run it over with a semi at least twice, not even a scratch.
