@FrankieS, thank you for the explanation. We will forward the information to SXK.

@valeriezxy, the SXK supplier still needs the video showing that the RTA you received is leaking. Could you please kindly take a short video and send it to us as per the instruction in the support ticket? Please understand that we indeed hope to help you solve the leaking issue of the RTA quickly. Your cooperation will be highly appreciated.
