The Jetbeam Jet-1 (cylindrical) takes an AA battery, and is almost a full inch longer, and a quarter inch wider. I would think a Jetbeam looks more like a "flashlight" in one's pocket, whether lit or not.
A Nitecore Tip appeals to someone looking for a thinner, "keychain"-size flashlight with a built-in rechargeable battery. Conveniently charges right alongside your smartphone. Let's face it, for pocket carry, if something isn't thin enough, it isn't going to make it into the EDC rotation. To be honest, my older-version one would turn on accidentally about once every week or two weeks. For me, it wasn't that big of a deal. With the 30-sec auto shutoff of the newer version, it's probably a non-issue now. I have lots of AAA and AA "mini" flashlights, but guess which flashlight actually goes on my keychain?
