I have recently got a Gus phenomenon lite. It is so good. Been looking for a mtl rta with build deck access bla bla bla. Its got everything I was looking for. The only problem is that chimney is a teeny tiny bit lose. Does anybody have this tank. The chimney occasionally slips when I a fiddling or filling up. It is a clone but the machining seems quite good otherwise. Would a slightly bigger oring up top sort things or is there something else I can do. Thanks
