I HAD TRIED LITERALY EVERY TYPE OF ECIG THAT THERE IS AND COULDN'T GET ON WITH ANY OF THEM UNTIL I WAS INTRODUCED TO VYPE. I AM USING THE E PEN AND ALTHOUGH I WORKED OUT THAT IT IS ACTUALLY ALTHOUGH IT IS MORE EXPENSIVE THAN ME SMOKING I KNOW IT IS HEALTHIER AND I HAVE TO GIVE UP SMOKING FOR HEALTH REASONS. I LOVE THE STRAWBERRY SMASH AND THE CRISP MINT CAPS, WITH THE CAPS IT IS SO MUCH EASIER AND CLEANER THAN SOME OF THE OTHER BRANDS OF ECIGS, THERE IS NO COIL TO REPLACE AND IF YOU ARE OUT FOR THE DAY YOU CAN TAKE A SPARE CAP WITH YOU AND REPLACE IT EASILY AND QUICKLY. LOVE IT SO MUCH.
