My search for the ultimate keychain flashlight is over. This $11 model does it all
Briefly

The article discusses the advantages of the Nitecore Tube 2.0 keychain flashlight, highlighting its portability, simple controls, and robust battery life. The author has preferred plastic flashlights due to their resistance to abrasion and notes that the Tube 2.0 supports multiple brightness levels, with impressive runtime and efficient standby. It features an easy on/off mechanism to prevent accidental activation in pockets and boasts a rechargeable battery life that lasts up to a year. After testing different keychain flashlights, the Tube 2.0 emerged as the favored choice due to its practical design and functionality.
I prefer a plastic or polymer flashlight to a metal one because they get seriously abraded.
The Tube 2.0 has an incredibly low current draw when in standby, allowing it to go a year between recharges.
