I am so sick of eleaf and their stupid Isticks....or atleast the ones I keep getting from my vape shope. I have gone through 6 total (4 30w and 2 50W). This has been all within 6 months. 30w I owned gave me an atty short error tried fixing multiple times with no luck.(yes I tried every o ring and prying trick I have read about) no luck still atty short every tank deck adaptor. FINALLY I said ok lets give the 50W a try for my all day vape. Not to found of its size although is smaller for a 50 first one I get fire button continually gets stuck and eventually stopped working. took it apart cleaned it out button was clicking still nothing tossed it bought a new one. this one I got about 2 weeks ago and again the fire button is not freaking working I'm so sick of this. you would think for the amount of money I spent eleaf would rectify my situations but nope not with out my original receipt even though I have my authentication stickers. NEVER BUYING ELEAF PRODUCTS AGAIN!!!!
