Comparable flashlights there are few on the market, and if so, they are significantly more expensive and usually considerably larger and heavier. Whereby the TN31 is anything but compact and lightweight. After all, she is 80 grams lighter than the TN32 with its weight of 720 grams (incl. Batteries), but you'd hardly notice.
Processing is probably subject to greater variations, as opposed to my immaculate TN32 is decentered something in TN31 of Bezel and the lighting levels Ring runs a little rough.
Unfortunately, as with the TN32 is, the battery cage a bit problematic. With most available on the market protected 18650 batteries, the lamp can not operate because the cage with inserted batteries is too thick for the battery tube. The ThruNite batteries fit easily, but you should the new 3.400er (red / white version) avoid because they are not resistant to high current, so that the light does not reach full brightness and burn time. The favorable ThruNite batteries with 3,200 mAh are much more powerful. Protected batteries you should be sure to use here because the TN31 has no warning function for discharged batteries. For operation with unprotected 18650 there is a risk that the batteries are empty sucked mercilessly, with all the associated risks in Li-ion batteries now there is time.
Conclusion: The TN31 is a real alternative to TN32 that approximately twice cost and barely visible light or remain lit.
Finally, a small request: You use the tuning button! So you contribute to a better orientation regarding usefulness of all reviews.
