I ordered mine 06/2019 (EU).
As i saw that people were starting to receive their units, i contacted realteus on facebook and emailed them, but no answer.
Then i sent email directly to Tomas (the owner?), also no answer for weeks. After waiting i sent one more email to him asking for some kind of reply, he sent me a tracking number (Gls group). At the moment the tracking says package is already in parcel center. I will update this post if/when i receive the product.
I think they are not sending the units in any kind of logical order, you just have to keep pushing them.
edit. Update 28/4, it has arrived.
