Do you mean the voltage +/- buttons? I don't hear or feel a mechanical 'click' when I activate mine so I assume this is what you mean.
I was thinking I'd really miss them too, but experience so far has shown me that I really am not changing the voltage that often, and when I do, hitting the single button repeatedly to get to menus and change settings isn't as tedious as it seemed from a distance/without the unit in my hand. Having said that, even if I did find it annoying, the quality of the
vape / the unit itself is so terrific that it more than compensates for that 'usability issue', in my personal opinion...
