I have been using a vape pen with disposable premade coils for a long time. Once I got this I was kicking my self for not making the leap sooner. This thing is AMAZING. If you’re using a traditional premade coil pen you will save soo much money on coils and you will experience TRUE flavor. Soo smooth and easy to use. 10/10!!! Bought it with a smart charger for 18650 batteries, quad core coils and wick n vape bacon prime cotton. A friend recommended I get all of these things, this is the best money I’ve ever spent on a vape. If you’re considering this vape I’d strongly recommend you buy the same stuff and try it out. I accidentally dry hit the bacon prime cotton and thought I ruined it, slide the cotton out. NO BURN MARKS! Great stuff all around!
