Hi friends I have a story, hopefully this can also help others who have or want the calabash atomizer. I usually use RBAS but I thought the calabash was pretty so I ordered one. The premade coil just didn't cut it for me so I decided to do a expirement. I had several old kanger coils from before I started building so I had a idea. I took apart the old kanger coil and rebuilt it into a micro coil. 6 wraps of 28 gauge, around my small screwdriver bit gave me a nice .7 sub ohm coil. I re wicked with cotton and went to see if it would fit into the calabash stem. It fit!!!!! I am now happily able to vape my calabash with more umph! I still have to keep the wattage fairly low at 15 watts but now this little atomizer rocks! Even at only 15 watts! It gives me good flavor and great vapor! And it's pretty too! So those who have or want the calabash, just know the kanger coils do fit and can be rebuilt to sub ohm if you wish! I was so excited about this I had to share with you all. I don't have very much "pretty" vape gear because I've always been more about functionality than looks but I'm happy to say now I have something pretty, and it's got the functionality that I like. I'm not much for premade coils as I always make my own but with some tweaking I have to say it's a darn good vape now! And it's pretty. The calabash I got is the crystal clear globes with the silver top and bottom cap and matching silver drip tip. For being all glass it's pretty strong. I do recommend one with some tweaking it can give a pretty darn good vape! Thanks for reading and I hope this helps someone else.
