Hey everyone, Ive been shopping around lately for a good keychain flashlight. Ive had my eye on the Maratac/ITP AAA flashlight but have a few concerns with it. I would prefer the AA version but Im not sure if that would be too big for keychain carry or not. So my first question is how would the AA version carry on a keychain? My second question is if there is any other flashlights I should consider. I want one that is all metal, small enough to carry on a keychain and forget about, uses either an AA or AAA battery, and has more than one power setting. Thanks in advance.
