Cloudnus by Vapeston which was made in 2016 has a very similar design to this one. Cloudnus is a smaller 25mm RDTA, but its goon style deck allows for larger coils. It is a bit difficult to wick, but once you get it right, it’s an amazing tank providing great flavor. I still use mine once in a while. I believe it’s still available for around $20 here. If you don’t mind a smaller size tank, don’t mind challenging wicking and like the design, you may want to look into it before you invest more on this tank.
