Hello, I have a rx mini and a uwell crown tank. At first I was getting Great flavor and clouds. Recently I bought from vista vapors and I noticed that their juice was burning up my coils and tasting very hot when used. I stopped putting that in my uwell and only use it in the rx mini tank that came with the starter kit. First why does it work with one and not the other and second my uwell seems now to only get dry hits with other fluids and leaves my throat feeling uncomfortable. Is thst because the rx mini can't handle the uwell or is the tank itself the issue. Any help would be appreciated.
