It is under $50 and yet a very compact, bright, and rather nice looking light. With 1 CR123 battery, it is just over 3 inches long and not very wide. It fits nicely in my front slacks pocket. It has decent battery life for the size/brightness and so is a good value for long term as well. You can also use rechargeable batteries in in which seem to increase the brightness without any noticable effects (I am waiting to hear on any longer term effects). Even so, at the price, it isn't the end of the world to buy a new one if something did happen.
In general it has received VERY positive reviews and mentions on here. Most people have been pleased with the brightness and tint of the light. Mine is very white and incredibly bright.
Hope that helps some...
