I now carry an Arc AAA PE for EDC but I must say I still like my Photons.  I still keep a Photon2 in my smallest kit and my wife keeps one on her keychain.  From what I have seen on the Photon website the new Freedom model looks very promising.  I might have to get one to replace the Photon2 in my smallest kit.  I had a 3rd Photon2 but my son got a hold of it.  Note to self: Photons are not toddlerproof! <img src="/images/graemlins/ooo.gif" alt="" />
