The generally cheap and crappy way most inexpensive vape gear is made is an issue but since 90% of everything is made in china with third world labor standards (if that), has a lot to do with that crappy machine work and bottom of the barrel QC .
I like high end hifi also. Lots and lots of Chinese made HiFi gear made today incorporate really great ideas but are poorly executed with lowest quality parts and no care or thought put into repair-ability or longevity. The manufacturer doesn't need it if the price reflects a disposable nature of the device.
Who fixes a TV now is another example I can go on about. Most fail due to $.02 capacitor failure.
I find the same with vaping hardware, Why make a Kanger coil either reliable or easily repairable if it can be made for pennies and sold over and over again as a disposable part that by nature is designd with a limited lifespan. When sold as such, the factory keeps humming along making more for pennies per unit.
It will take us, the tinkers, the hobbyists, the basement workshop innovators to move things like that along. Fighting the "screw it, its cheap to replace" mentality is the hurdle.
Just my humble opinion and I may be wrong.
I'm liking my cheap, Chinese Kanger stuff right now and trying not to do my share to keep the big american tobacco "innovators" well fed anymore at least!
Instead, figuring out how to repair this cheap vaping stuff is not that hard with some patience and I was gonna tinker anyway!
Not knocking High End vape gear at all. Take the US made Provari for example. Expensive for what it is, But, I have never seen a complaint about poor thread machining, or lack of customer support. You pay somebody to give a crap about what goes out from the production floor, actually inspect the finished product and don't run substandard leftovers on the line overnight, the product is almost universally flawless. Reflected in the price of course. Continuing support, care in manufacture and high standards are what you are actually paying for with something like that.
Cheap comes with a price most of the time, the corners get cut somewhere.
So many great ideas are hobbled by the goal of $.30 per unit goals.
