Pros: Durability, Bulb Durability, Brightness
It's a Surefire...what else can I say?
Bought for my wife - she works outside at night to avoid the heat and bugs, and she doesn't like headlamps. She had tied her Nightcore to herself in many, many hilarious ways, and I finally decided to solve her problems for her. She loves it! The beam is less focused than we thought it would be, but that's a good thing in this case. The High/Med/Low settings are also perfect for her. My Surefire is H/L only, and I always wish I had a Med setting. The jury is out on burn time, seems a little less than stated, but we have not timed it yet. Being rechargeable is also nice in this case. I will always have a Surefire nearby!
