I bought the 2AA model the second I saw it at Wal-Mart, and it has not let me down. It delivers amazing light, great regulation, and is built like a tank. And the ease of replacing it is a huge selling point for me. For instance, I love my Fenix L2P, but given it's price, and the fact that you have to order online to get it, has me using the Mini-MagLED 2AA as my primary light source when on the go. The fact that it's so affordable, and so easy to replace if it gets stolen/lost (You'll note I did not include the word broken, because every Mag-Lite I have own has been beaten up so much, yet works like new), was a great selling point. Thanks to the huge popularity of Mag-Lite flashlights, this will definately get the word of LEDs out to those who think that their incan. pocket light is as good as any of the LED lights. And I can't help but to love the Mag-Lite 4D LED bulb.
