Been using the Ijoy Trendvapes v8 clearomizer and it's great. It blows the PT3 away. Its completly solid stainless steel, not copper chrome plate, and has pyrex glass inside and four windows to see how full it is. Even the dual coil is solid stainless steel and I've been using the same coil for over three weeks. It holds four ml of liquid and has a adjustable airflow base. Its big and heavy, almost to big really but I like it a lot. I like it so much I also got the Trendvapes S6 which is a smaller version with ego threading and holds two ml of liquid. My seller just got these in recently and the entire Trendvapes line of clearomizers all use the same dual cross coils which is great.
