It comes in a nice cardboard box, and includes diffuser, manual, and spare o-rings. The batteries fit snugly inside the tube, so some wider cells might not fit, on the other hand this way they don't rattle. The button is a bit stiff, and I don't always know if I clicked or half-clicked.

Modes

This flashlight has 3 modes, Medium (25 lumens, 25 hours), Low (1.5 lumens, 50 hours), and High (125 lumens, 35 minutes) in this order. The medium mode is the default and has a good balance between brightness and runtime. The high mode is nice to have, although the shorter runtime limits its use. I find the low mode too low to be useful in general, and the order of the modes is not intuitive. I often wonder if I switched the light off or if I just switched it to low.

Conclusion

Pros:

Inexpensive

Lightweight

Cons:

Mode order

Low is too low for me

Given its small size and weight it's useful as a backup, but I don't recommend it as your main EDC.
