I got my Massdrop Brass AAA on Friday! Not long before that, I got the Lumintop Ti Tool AAA on which the Massdrop flashlight is based. Both lights are about the same length as my Preon ReVO SS, and the titanium version is actually lighter. They are slightly larger in diameter, but only on the bezel and tailcap, which actually makes the light easier to use. The brass has my preferred mode sequence of L > M > H, though the low is not a moonlight level like the ReVO. The titanium has a M > L > H sequence, but I find myself preferring the Medium level for normal, non-nightstand use. These lights could probably just be used for keychain service if you are willing to tolerate a little bit of extra length for a clicky. @reppans Sorry, but I may be bailing on the Preon ReVO SS club due to these new flashlights.
