I took the bait and purchased the Goblin mini after being defeated by trying to build my own Nickel coils. I wasn't have much luck with the Crown either. Seems that mine leaked a lot and it didn't matter if I wicked using the S pattern or the pancake method. The pre-built coils just seemed to last me a few days before I noticed that I needed to change them out. This is mostly due to the type of e-juice I use at 35% VG/ 65% PG. I like it like this because IMHO it give me the best flavor. I don't like heavy VG e-juice. This could be the reason for the leakage as well. As I mentioned in another post, I need to cut the cost down and building my own is much cheaper than buying pre-made coils and going through coils in 3-4 days. So far, I love my Goblin mini. The flavor is awesome. No dry hits yet and I can vape my e-juice until the tank is empty. The only con is that I no longer use TC on my mode. However, I wasn't having the best vape experience using TC. I often noticed that after a few days of heavy vape, my vapor would become cool and I would have to increase the temperature until finally I would just get frustrated and changed the coil or switched out the coil to return to power mode. Perhaps someday, I give a try to build nickle on the Goblin mini. But, for now, I'm using Power mode and loving it. 50W @ 0.27 Ohms.
