At first I was really shying away from rebuildables, but the guy at the shop showed me how easy it really is, and much cheaper than the coils I had to buy. My first impression was I noticed a more pronounced flavor, with less sweetness. This It seems to burn juice a lot faster. I have a tendency to chain vape, and this gives me much more nicotine faster, but primarily I like a slower burn, and more for flavor. after hitting it a bunch of times, the juice consumption seems way too much for my liking and I got sort of a burnt taste when I tried to put a higher wattage in an attempt to ramp up flavor. The cost in the long run, way cheaper than buying coil packs, is why I bought it. But I'm kinda sad, it's lacking the flavor and sweetness of my mesh coils. I was gonna buy a crown 5, but then the RTA seemed like a better option. The coil cost is much cheaper for sure, but I'm not too happy with it.... I felt a little awkward telling the guy at the shop, as he's the one who went through the trouble to show me how to install the coil and everything, cause he uses one. I'm now wondering if I should have just got the crown 5 and paid more for coils.... Idk. I don't like spending a lot of money, especially if I end up not really liking something. It's not the shops fault, they're one of the best ones I've been to. He even gave me some freebies, which was awesome. I would appreciate some input from other RTA users as far as your experience with builds. Thank you in advance.
