That's unheard of, if there really is a known quality control issue, the company should provide backshipping(if for no other reason then just to make sure the bad product is out of the public circulation). They should have wanted to get it back so they could verify the lot and do their own testing on it. As well as to make sure it was properly disposed of. Could you imagine McNeil labs making the customers pay for the backshipping on the poison Tylenol bottles back in the early 80's.(I know it's not the same level of seriousness but still, c'mon)
They were going to re-imburse me, but that wasn't the point. I didn't feel like paying out that kind of cash, even for a short time: Even Johnson Creek sent me a FedEx label to box up and schedule a pickup time for three bottles I returned. They were also very gracious, and I felt really bad but could not tolerate the 30% PG.
I do have one more point to make about the ECOpure Krystal, I haven't bought or tried the flavors at all, but the Krystal (and apparently by labels, all other VG based flavors) does contain Ethyl Maltol, which should smell very sweet and a little caramel scented...it tastes very bitter but smells sweet. The nicotine in bitter also, but should not have a scent really at all. The bottle I have does have a scent almost like acid. It's not real strong, and vapes fine, that smell doesn't come through in the vapor as a taste. ?? After it sits for a minute, that smell is no longer there. (Or, did my nose burn out!) So I tried it a few times, check it in a couple days, same thing. Leave the lid off a few minutes, it's ok. I have had no negative or ill effects from using it, and have been using it exclusively for a couple weeks+ now. The juice in my needle bottle I use for mixing does not smell like the big bottle does, it is air tight as well.
So what these smells are coming from is anyone's guess, I would think it time for them to come through with an explanation. If this doesn't turn around FAST, they will have no market left. This is supposed to be the world's most TESTED product available, so what is this awful smell. How this can happen, are they passing out old product, if so who is the tester here, a qualified Lab or the customers.
SO: Try to leave your lids off for just a few minutes, and see if that odor goes away in off gassing. I'm also going to make another of my famous e-mails I know they love to get (Not!) and see if I get an answer. It's a puzzlement to me.
