I started off with the Titan when it first came out.... good
throat hit, great vapour but occasionally a little tempremental... I decided to by an Evo intially as a backup but find that I prefer it... good quality build, battery life is good, vapour and
throat hit good... the only issue is filling the carts is not as easy... which is leading me to buying the pre filled carts... but for me the Evo out of the 2 is the better unit
