I have a whole slew of Streamlights that I've purchased over the years. Stylus® Penlights that I use for light painting in my photography; Stylus Pro®, Stinger® and Survivors® that I used on the fire department for 26 years; and my favorite the MicroStream® which is in my pocket every day. Last year I lost my MicroStream and immediately purchased a second one. Recently while doing some yard work I found my lost light. It had spent a Minnesota fall, winter, and spring in the yard. It has a gash on the bezel from the lawnmower and was covered in mud. I popped in a fresh battery and it fired right up! I'm a firm believer that you get what you pay for and I'm a Streamlight user for life!
