I posted earlier last week that I'm having problems with atomizers lasting on the provari. Someone posted a ohms/voltage chart and I've been following it. I ordered a 3 ohm Cisco spec atomizer from Avid Vaper for around $8 and a 2.5 ohm to try out for the Provari. I also picked up 2 of the 1.5 ohm attys for my Silver Bullet. Overall it costed me about $50 bucks for 4 306 attys and a new drip tip. I totally feel ripped off!!! The 3 ohm atty on the Provari lasted 4 days and burned out. I was vaping at 3.7 volts and moved it up to 4.2 volts. It worked great and then all of a sudden stopped working! The atomizer coil got red hot and burned out during the last few hits I got out of it. What is the problem? I definitely haven't let the atty dry out. I constantly add drops when the flavor diminishes. Am I just having bad luck with these atomizers or possibly getting defective attys? I don't think I'll be ordering from them again since this is probably the 5th atty that burned out in less than a week. The 1.5 Cisco spec atty I'm using on the silver bullet has lasted over a month now but I've gone through a couple that only lasted a little over a week. It's getting ridiculous!!! Can any of you direct me to a good vendor to buy attys from in bulk for a reasonable price? I like the 306's but willing to try other types if they last longer and vape just as good. I'm not ready to get into Rebuildable attys just yet but doing research on it. I really just want to find cheaper and longer lasting attys over 2.0 ohms for my Provari and the low voltage 1.5 ohm attys for the Silver Bullet. As of now the Cisco Spec attys from Avid Vaper are crap in my opinion!!! They work great if they work but lasting less than a week is beyond horrible for the price they cost! Only got 2 good ones from them so far that lasted over a month and they are the 1.5 ohms being used on my SB! So 2 good attys out of 10 ordered in total in the last few months at around $8 dollars an atty! That's some major BS!!! I need to make an order from somewhere soon! I seriously don't trust the attys I have to last very long!!! Please help!!! Post the type and ohm of atty you use on your Provari?, what voltage you vape at?, and where you buy your attys from please? Thanks!!!
