Hey guys, im having a problem that i dont have much experience with; a bad ebay seller.. i bought the Davinci vape on ebay for 100 bucks plus shipping, i bid for the item. i got it a couple days ago and only used it once. i turn it on last night and i instantly fall in love with it, its awesome and worked how it's supposed to work. then later that night i was going to hit it up before bed when all of a sudden the red light that lets you know it's heating up starting blinking instead of flashing solid and it wont heat up. the buttons wont do anything (power button, lower/higher temperature buttons). it just stays at 375F but wont heat up. its completely broken and nothing will fix it. my real question is: can i do anything about this? i dont recall the seller writing a description, only posted 3-4 pictures of it and was stated as used. but he didnt write anything about it being defected and im almost positive he was just trying to sell a broken product. back when i ordered it i asked about it, and his reply was his brother used it once, didnt like it, so he's selling it. Any feedback is SUPER appreciated, sorry for the long post. TL;DR : can i do anything about a guy who sold me a broken vape on ebay?
