I agree with Major911 after 2 days with the cloupor mini. It's very solid in material and finish. heavy and much more of a dense feel compared with istick, none of the way the istick feels like multiple parts of different material being assembled together. Kind of like the feel of a single piece aluminum mac laptop if you are familar, zero flex or creak. The solidness is evident if you slide the battery cover down a half inch and let the magnets snap it back into place, a satisfying and addictive snap -- here I'll make the analogy of a 1980s ford car door slaming shut versus a similar era honda (before american manufacturing quality came back) -- snap! no clunk, no noise as the cover finds it's place, just one tight click as one part finds its perfect seat with the other. Yes, I have a very slight play sideways if I torque the battery cover to try to find it, it does not occur in regular use.
The .8 second delay from sleep: It's there, I feel like you either fall into the unconscious habit of clicking the fire button when you pick it up after a while as I did, eliminating the perceived delay or it will annoy you until you do.
Adjustable non-spring pin: Fit everything I threw at it no problem. I made one adjustment only between a series of kayfuns. As phil mentioned, the way the center pin assembly is installed it is raised just a tiny quarter mm above the surrounding device body. OCD folk may care; I don't. The pin and threads seems extremely solid, back-threading to start putting a topper on yields a tight, audible click that feels and sounds as solid if not a little more than on the vaporshark, not sloppy and soft like the istick20.
Battery life: Samsung 22r lasted all day and into the evening when I swapped it out with meter showing about 1/4 full.
Outside finish: it really seems impervious to fingerprints and as scratch resistant as my vaporshark dna30. I have scratched my VS a little through my own fault, so far no issues on the cloupor. It's very grippy in the hand and has the batter cover pips and the ribbing on the side. I don't feel I would want a skin on it since it feels so good in hand. It's a little wider than the istick, pretty much exactly same as vs 30. Rounded edges but still square. Great size and feel.
Oh. My up/down buttons have the slightest of rattles when I shake the device. fire button has no rattle or movement. Power settings and accuracy seem right in line with the Vaporshark. For me, this is a big winner.
