Hey I'm looking for suggestions regarding a really tough E-Cig for my 18 yr old son. He's been smoking for a couple of yrs, and to those wondering I did not approve. He's been taking drags off my Janty Stick every chance he can get but He doesn't have money to buy his own so I'm gonna get him one, The problem is he's tough on things including his own MP3 players and Cell phones so I want to find something tough for him, something that if he drops will keep on truckin. Any suggestions appreciated, Thanks.
