That's awesome! Kudos to your local shop, sounds like you've got a good one. I think all these mods are mass produced and they're constantly being upgraded so it's a bit of a mad rush. I agree, it's a solid little mod and plenty for what I use it for. So far everything's worked properly on mine though I haven't pushed it to its limits.
Currently I'm using it with an ehpro bachelor single coil rta. Running stainless steel 28ga, my current coil is a twisted pair of 28ga ss316L at around 6 or 7 wraps comes out to .63ohms. More of a flavor chaser than a cloud chaser but it works pretty well for me. Usually I vape it between 25-30w, I tried 40-50w a couple times to see what it would do and the vape was way too hot for me. Paired with a ton of spitback and popping so I lowered it back down. The only time I really set it to 35w or so is in tc mode so it ramps up a little faster but even then I keep my tc at around 320-330F. I just prefer a cooler vape.
The only real con I've seen is paint seems to chip off it a bit easy. Seems to plague a lot of them though, I've seen vtc's with paint chipping, kanger mod's all nicked and paint chipped. Doesn't seem to matter if they're $30 mods or $70 mods. Most of these places I think get their mods from the same manufacturer, for instance the istick 100w. It's nearly identical to the kbox 120w. The istick 50w with built in battery is identical to the halo reactor mod at least from what I can tell.
