I am so impressed with the Tac Light!  It is a really bright flashlight with many different functions.  I like that you can easily zoom the flashlight in and out.  When you zoom the flashlight fully out you can see a very wide area and when you have it zoomed in it is perfect for seeing in small spaces.  There are is also a strobe mode and SOS mode which makes the light constantly flash.  The flashlight is very durable and perfect for outdoor activities or to use while working.  It requires three AAA batteries which makes it easy to replace them without needed a special type of battery.  I really like this flashlight and how well it works.
