I am very happy with the Thrunite TN4A.I bought it after reading Selfbuilt's 4xAA reviews, it has great mode spacing, long run times, combination of great throw and spill, is well built, has battery life indicator, and available in neutral white. That's just the beginning, check out his review for all the info. For me personally, it has more than met my needs for just about any circumstance. There are reviews on youtube where they "torture" them as well, e.g. throwing them around, freezing them in water, etc.
