Hi, Jane Li
I am Ryan and nice to see you.
How did you know R&D Tech is doing business Sniffer4D in korea ? I like to know about it throuh Youtube, Blogs.

And I'm sorry for the late reply.
We can supply Sniffer4D to you in Singapore, but we have to ask our headquarters if we can supply it to Singapore.
Instead, I will inform Chinese Soarability manufacturer of your information so you can contact me.

Best Regards,
Ryan
