I think a lot of it does depends on how much time you want to spend dickin' around with returning the products under warranty. For me personally, I can't be bothered with it. I'm more of a "disposable" person.
For example, I use a different atomizer for each flavor I vape. So at any given time, I have 10 atomizers around....some black, white and silver. If a couple die, I just order more to replace them....although I have only had 2 die since I started vaping and now I'm not even sure those were totally dead as I have seen some miraculously spring back to life. Wish I had kept them now to experiment...sigh. In any event, I would have no desire to keep track of them, the original packaging, invoice, etc....whatever it takes to return an item...every time one died. Too much hassle for me.
But, on the flip side....once I ever decide on a product I think I want for life...well, maybe that will be different. But I don't know what that is yet.
Kind of reminds me of my cellphone. Every 2 years I get a newer model when I reactivate my account. I don't care about warranty as long as the thing lasts the 2 years. So I'd rather pay $100 with a shorter warranty than $300 for something that would have a 5 year warranty because most likely, I will not be keeping it that long. I've still got another year and I'm already looking at my next model. And since they keep coming out with something better, I don't know if that will ever be different!
