I like my 2xAA MiniMag 3 watt LED. It is solidly constructed. As with all MiniMags (and fullsized Mags for that matter) the head will feel a bit loose when you screw it out to focus the beam. I wish Mag would use a tighter thread pattern to alleviate this. I find the 3W MiniMag a great replacement for a fullsized 3 D-cell Mag with incandescent bulb. I have many many LED lights, and this 3W LED MiniMag is the first I've owned that has a decent throw - on par with an incandescent Mag. The beam of the LED MiniMag is much smoother (and whiter) than the incandescent Mag. With the incandescents, you get to see all the internal wiring inside the bulb and other artifacts projected. Not so with the LED MiniMag. The head screws all the way off for "candle mode". The light will stand upright on it's tailcap, but being tall and skinny you shouldn't expect it to stay upright after even a minor jarring.

I am still on my first set of batteries with this new light, but I have read that the LED MiniMags are very regulated - meaning the light stays at the same brightness right up until the batteries are exhausted, where the MiniMag simply turns off unexpectedly. If what I've read is true, you may not want this light if you desire a warning period of lower light output when your batteries start dieing. I actually prefer the full brightness until death output, since I always carry a single AAA led light on my keyring as a backup.

The MiniMag LED is on my list of "would buy it again". Not all of my other lights qualify for that. You need brightness, quality, durability, and reasonable price to qualify for a "would repurchase" recommendation in my book. The 2xAA MiniMag 3 watt LED qualifies. I do not have experience with the AAA models. I assume they'd be similar to the 2xAA, just with reduced runtime.
