I emailed them after learning that other offerings (which i almost bought) are breaking after a couple of weeks.. Here's what they told me. just an FYI.
Thanks for your contacting.
We are waiting for the Smoore factory to start producing the USB passthroughs for M series. It's estimated we can supply such products in the fourth week of this month. The USB passthroughs for M series supplied by other vendors are not the original products produced by Smoore.
Hope you can always be satisfied with our products and service.
Yours sincerely,
Heaven Gifts
i will be ordering..
