I spy with my little eyes: Someone that hasn't been paying attention to the world. When a new product comes out (like electronic handheld vaporizers. They're pretty fucking new, if you think about it. Nonbutane powered vapes really only started to show up about 5 year ago), there are bound to be problems. As time goes on, those problems get sorted out. A company releases it's initial product, it works well but has some kinks to work out, then it releases it's second product and it's even better. You think 100 years ago (not quite 100 years, but you get my point) your precious toyotas worked as well as they do now? No fucking way! They were shit, just like all cars. But, over time, they released more and more new models and with each new model they addressed more and more issues. That's how life works. You try something, it doesn't work as well as you'd like, so you improve upon it. That's why you BETA TEST (which is, in reality, what the backers are), so you can iron out problems. You think the first ever cell phone was perfect? No, it wasn't. They fucked up all the time. The first computers? Not only did they fuck up all the time, you needed an entire warehouse to store them. You get my point? It's a fairly new industry with it's fair share of problems and every year more and more of them become non-issues. I've never seen a company that doesn't offer at least a 5 year warranty on it's products. If it fucks up, you get it fixed and move on with your life, just like you do when your car breaks down (which still happens all the time, so all of your arguments are effectively invalid). If you don't like that, get out. We won't miss you.
I'm definitely getting in trouble for this comment. Oh well, worth it.
