This discussion is about the "intellectual property" of a flashlight with a 510 connector???
Check the ECF Modders forum from about 3, 3 1/2 years ago, mech mods are not "intellectual property" of any company, unless they are paying royalties to a lot of modders. The designs and "intellectual property" are very old. Etching a brand on to the design, in branding not a design improvement.
VV/VW suffer the same fate, early vaping was battery voltage only, modders developed VV, VW, PWM applications.
(thank you, thank you, all modders!!)
