Ok, I promised an update regarding the way I'll handle warranty.
On my store I specifically only mention DOAs an the return policy for those. The reason being, I can deal with my supplier to get those dealt with easily so long as I know quick enough, etc.
I left a warranty off the site for a couple of specific reasons. 1. To protect myself and my business legally and 2. to protect the customers from being held to a specific set of terms. The protect myself should be pretty obvious. I wrote up a number of different warranty options and ran them through my lawyer and theres just no way to write a functional warranty that doesn't open me up to a large variety of potential legal actions.
Leaving it off though means I can handle each case personally and handle it in the best interests of the customer. If I said "All defective items will be replaced" maybe you decided you didn't like that product anymore and don't want it replaced, you want 'other' stuff I sell... I can give you store credit because I'm not locked into any form of contract. Say you just want a refund... I can do that.
People will read a warranty and see all the crap I'd have to add to be legally viable and say "This warranty sucks!" and lets face it, warranties do suck. They're mostly pointless and when held to the letter, they're not useful to the business nor the consumer.
My plan is to handle you each like I would handle my friends and family, as I've stated numerous times, I want to get people
vaping and keep them
vaping.
Regarding the zmax specifically... It is my "top end" device on the store right now and if another device that I feel more strongly about appears on the market it might get replaced. If the device fails prematurely I will take care of you. If it's DOA (hopefully not!) I will take care of you. If you abuse the product and it does... hell, I'll probably just educate you on proper use and then take care of you

Like I said, I want you guys
vaping and I want you to recommend me to your friends/family/hobo you saw with a smart phone and a cigarette. So I'm gonna do everything in my power to take care of you and specifically YOU based on the situation.
I've got multiple outlets for people to get in touch with me, between the phone number/address/contact us on the store, to my blog, facebook, here on ECF, and on ECF live chat. Hopefully we don't have many situations where warranty issues even get asked, but let's be honest... it is still a mass produced item and sometimes things will slip through. Just know I'll do what I can to make your situation right as fast as possible.
