I just got my TT-3 this afternoon but had to wait until tonight to really give it a workout. Right out of the box, the quality is evident - but you would expect that for the money. The light is superb - I wish I had had it the last time I was sailing at night and looking for navigation markers in the dark. I sure will next time. But it is the little things that earned 5 stars for me. The spare switch cover and O-rings; the fact that it comes with a holster and a lanyard and a spring clip; the guards on either side of the switch that discourage accidental activation. If you want a top of the line light, I don't think you can do much better.
Ordered one of these on sale elsewhere for about half the price than found here. Very impressed for the price I paid ($30) with solid aluminum construction and love the tail cap actuation with two switches for on/off and brightness mode. I have several flashlights that use CR123 and 18650 batteries, so for the price I wanted to see how this model with AA batteries would work.
Can't give it 5 stars because of the audible induction whine that the circuitry emits when the flashlight is on. Didn't notice it at first but when I took several flashlights out to compare one night, I noticed that all three of the Terralux flashlights (2 TT-4 and 1 TT-3) had the whine. I have read it doesn't affect the light in any way just something about certain brands of lights that are more noticeable than other.
If you get it at a good price, I would recommend it as a nice AA battery flashlight.
I was using it on the 4th of July while lighting fireworks in the back yard and accidentally left it out there. Found it 2 weeks later while cutting the grass. In between were multiple day long thunderstorms. Picked it up, brushed the mud off, and it ran good as new.
The bright setting is so strong it can hurt your eyes, it never seems to need new batteries, and as I've discovered it's incredibly durable.
Nice bright, white light with all the features listed. Durable and easy to switch between modes. I use this light every night at work and am very impressed. Using just 2 AA batteries and getting a high light output is nice.
