Hi , I've had a chat with our general manager and we no longer have any kits of that model left in order to source you an exact replacement tank , I know you said you were enjoying the mod so would you be happy enough to accept a different tank that is similar in performance . I would suggest the Uwell Crown 4. We have it in , Rainbow Iridescent, Stainless Steel and Green Iridescent, sadly black is out of stock . You can view it at this link: https://ziggicig.com/shop/uwell-crown-4-tank-1 . If you're happy enough with one of those , just me know which colour and I'll arrange for it to be sent out. This tank features a similar mesh style coil to the sigelei tank but with an additional dual parallel variation available as well. The power requirements are almost identical. So it should work well with the device. Let me know and I'll get that sorted for you. Thanks
