Absolutely Perfect in every way !!!
"The Nitecore HA15-UHE is so light & bright, I promise you will forget you're wearing it. The 2 function power buttons work very well in conjunction with each other, The button on the right for on/off & brightness levels. The left for RED, SOS, & STROBE. You will need to purchase a 14500 Li-ion rechargeable battery if you wish to utilize the brightest modes of up to 400 Lumens though, it does come with an alkaline AA battery included. There is a rubber cover that is very easy to open to install the single AA battery. I love the AA battery as opposed to the AAA battery for its longevity. There isn't a USB port of any kind, the rechargeable battery must be removed for charging. I really don't mind that as the run time is far greater than I expected. I purchased two of them."
