I did a brief check on aliexpress and alibaba and can’t find them but I’m sure they’re out there somewhere
There's a company called Seatorch on AliE that makes an XR15 clone (LM-15), an XR30 clone (LM-30) and one in the middle (LM-25).
They're more expensive than the X30/A8, but seem a little better quality with a better app.
