Anyone heard of this before or even tried it out?
The first sub 1000€ gravimetric grinder I have seen.

Do you mean the RF64W, a.k.a. ZF64W - Automatic weighing grinder with zero retention and 64mm burrs

If so, then I believe that it is from the same company that makes the DF64. Looks good on YouTube ...

Terribly sorry... I forgot the link. Friday night mistakes... here: https://wb.coffee/product/pro-barista- ... o-grinder/
" Pro Barista G-Risto Titanium on demand Espresso grinder" (whew!) they call it.
... but yes, you are right! It looks the same.

Edit: and after looking more at your linked thread, it is definitely the same. It figures, with all those different names it should be a Chinese (or, which I would have preferred, a Spanish one... maybe Eureka comes out with something similar, like a Mignon with gravimetric add-on...)

The "Caffe Martella Singapore" YouTube channel has some videos using the grinder:

Not the first one for sure if you only mean "grinder with a scale under 1k". The Baratza Sette 270wi was released some time ago. But if you meant with that kind of burr, then probably is the first.

I just meant it was the first sub 1000 I had seen. Obviously not quite up to par, or with my finger on the latest products...

The Sette gravimetrics solution was much neater as well. Thanks for the heads up.

I have one, as do one or two others on H-B. We've posted reviews of a sort. This recent thread (which is running off topic) Are two grinders necessary? has links on page 2. I also have a Sette 270Wi, which as noted is gravimetric. The ZF64 (and its aliases) will still be going when the Sette is dead and buried...built like a cement mixer. The ZF64 is much quieter and is flat burrs. Its steps are a bit coarse for espresso, but that's what I use it for anyway.
