I'm one of those guys who just doesn't get why anyone would want to kick a mech in the first place. I mean, a 10w limit and the first gen kicks cost more than a vamo!?!?
In response to the first part of your statement, people do it because they want a regulated vape from a mechanical device... As to the second part of your response, most Vamo, V/Zmax, Evic, & (insert any other failed VV/VW devices here), vape between 7-10 watts and are very happy with the vape. This is where just about any mechanical and an installed Kick come into play! Most people are curious about mechanical's and RBA's but don't either know how to or can't set them up properly and consistently to get the same vape they were getting with their VV/VW devices. You also have those people that don't have an interest in rebuilding their own coils, (for whatever reason), and would rather use just a standard atty or carto on their device and again this is where the Kick installed is the viable option for them.
I am one of those people that enjoys my vape at 9-10 watts and I can just set the Kick, install it, and vape happily, (and consistently), all day... I also own other mechanical's and have RBA's on them and have tried the sub-ohm coils and IMO, its nothing to write home about.
The same feeling you have about not understanding why someone would want to kick a mechanical, I don't understand why anyone would want to vape sub-ohm coils!!! To me its a step back in time, prior to VV/VW, with vaping and the draining of the battery leaving me with an unsatisfied vape and wanting to pick up an analog!!! At least with using the Kick installed I don't have that craving!!!
Something to remember, what makes your vape enjoyable to you is usually not going to be the same for someone else... Its not rocket science!!!
