Very nice !
Yeah you never really know if you don't try it for some time !
For example : I was early on rtas since the Expromizer 1.2 and Kayfun Lite Plus and i was pretty good, but later on i got o few rdas and later a Nautilus 2s and they are working perfectly ! A few months ago when i got my Zelos X80 they gave me an Innokin GO Z as a gift and also was working very nice, so im keep it as a backup... !
