I got mine in the mail yesterday. I ordered it Tuesday night off of eBay. It came with a .25 dual coil in it, and a spare .25 and .5. I've went thru about a full tank so far. I started with a delta 2, then I had an Atlantis, then I had the herakles v2. The crown has them all beat by a very wide margin. The clouds are a lot like the herakles, but the vape is so much cooler. The herakles did seem to have a little bit of an edge flavor wise, but the crown still tastes great. But I hate the heat of the herakles, so I'll gladly sacrifice a lil flavor for a more pleasurable experience. Overall, I'm highly impressed with the crown, and I highly recommend it. Philthememman on eBay is who I got mine from. Mainly because they were the only one I found that had 2 .25 and a .5 coil as opposed to a .25/.5/ and a .15 tc coil. Its definitely as good as they claim. And as far as ohms jumping, mine goes from a .2-.3. So no real big problem for me. I love this thing. Btw, it was $30 shipped and got here in 4 days
