Tank - depends on what you mean by better. It's a study unit. The battery lasts 12 to 14 hours for my husband, who vapes all day long (as in leaves his hand to go to the bathroom and that's about it). It puts out a cloud of vapor at 3.7v. Way more than one of the other 3.7v in my siggy. I dropped mine at work on a concrete floor (fell out of my pocket) , it hit the bottem edge. If you look you can see a teeny tiny abrasion, but if you rub your hand over it you can't feel it. I won't be one bit surprised if it dissappears when I polish it. Fires every time and I mean every time. Manual button is sturdy, no little stick on plastic strip over a metal piece. It's a real button. Hope you like yours at least half as much as my husband and I like ours.
