Unfortunately I decided to order my Vape pens (2) from Element Vape. I have used this exact brand/style for more than 3 years. I usually purchase elsewhere and NEVER had an issue. So I was surprised that immediately out of the box there was a problem ... I threw out a brand new coil and tried another one thinking that was the issue it was not.. So what I thought would be not a big deal... explain the situation ....exchange it good to go.... but nope After multiple emails ... finally with an email from them asking me for a video of “ air flow problem” which please explain how I show air in a video ... when I asked them that exact question the next response was Unfortunately, airflow issues are not covered under our 30-Day Limited Warranty. As this issue can be caused by many factors. We apologize for any inconvenience and appreciate your understanding. Now this was BRAND NEW JUST DELIVERED ... that is how they handle a defective product. So purchase at your own risk... I’ll go back to where I have never had an issue purchasing the same item...
