Just out of curiosity what did you run across that wasn't warrantied?
I only ask because I've had a couple purchases that were warrantied and am curious of what to steer clear of. I know for sure their arizer's and hammers are honored. I've had excellent experiences with vaporseller, but admittedly have never needed to try out their CS.
It's been a good while since I checked, but their pricing on VapeXhale and Davinci products was suspiciously low, and I know those two vape makers were (are?) strict on buying from authorized dealers. Any model/brand selling for less than you see elsewhere should be questioned. When I sent the company an email, questioning the warranty on some of the products, due to their lower than low pricing, I was told that lower prices made up for the lack of a warranty, so they weren't claiming to be authorized for all their products. The problem is that a lot of dealers will list the manuf. warranty terms, as if you'll be covered, but that may not be true.
If you value a warranty, it's always best to contact the manufacturer and ask about their policy. Some don't care who you buy from, and others require the purchase to be from an authorized dealer. If you can't get a clear and prompt answer from the manuf., maybe you don't want to be considering that brand at all, unless a product guarantee is not a concern. Some dealers will offer their own warranty in place of the manufacturer's, but that's a lot more iffy than one coming from the company that made the vape.
