Light is EZ on batteries, small, light, tough casing.
I have used it for five months. The clip deformed the first few months and I had to break out my tools to re-bend it. The clip attachment is also poorly designed. I can see the pocket clip failing within the first year. Not too good for being pampered in a pocket.
The switch is also problematic--sometimes requiring an excessive amount of force to get beyond the momentary and "on". Momentary is good. Same issue trying to switch "off"--excessive force needed. Or you need to hit it just off center with a fingertip only--not easy when wearing gloves or holding with hand and activating with thumb.
Buy something else.
Pros: Small, light, bright
Cons: Poor switch and clip
