I have the snow wolf 200 watt and then i bought the V1.5 and had to return 3 of them b/c I could not vape any of my tanks below 500F on all 3 and I do not build my own coils. I was looking at this but since my V1.5 purchases did not go so well I was waiting to see since I heard it is similar to the SW 200 Watt V1.5. Any feed back would be greatly appreciated.
