At less than six inches it is easily carried in your pocket and it's thin cross section will not disturb your everyday activities. This is not an extremely bright light at only 48 lumens compared to other lights which provide hundreds of lumens. This is more for the situations where you need a light quick and fast and not for big jobs where a lot of brightness is needed. Overall it is plenty bright for most jobs.
One thing I like about it is that it is powered by "AAA" batteries. Usually EDC type flashlights have some weird type of battery that can make them hard to find some times. This is not the case with the Streamlight Stylus Pro.
Also the batteries will last a for more than 6 hours of continuous use. Some of the other EDC lights might be brighter but you will pay on use time. Many of them offer less than an hour of use at their brightest.
The switch is on the back of the of the flashlight. I like that that option because I have found out on other everyday carry lights that having the switch on the side of the flashlight, they can turn on by themselves in your pockets. This will not be the case.
The Stylus Pro is constructed of durable aircraft aluminum. That makes it pretty tough and it can withstands drops from up to 2 meters. The lens is made of durable polycarbonate. And it is weather proof.
Also the Stylus Pro has a pocket clip. This makes it easy to keep in your pocket and have quick access to it.
Overall this is a good little light and you won't have to break the bank for one. I would say this is mostly a light for small jobs where not a light is needed and as a backup type of light. You can get it HERE.
