Crushgrind mechanism available in 2 variants

A number of months ago I emailed Crushgrid and received the following information which may be useful
Crushgrind make 2 mechanisms the Diamond and Quatro

If you buy from one of our partners in UK it is the CrushGrind Diamond mechanism.
I am not sure we deliver to Snainton directly, but I had a look at their website and the pictures show the Diamond version.

But actually, the guarantee and dimensions are the same on Diamond and Quadro.
The Quadro is our latest and patented version. But as mentioned this is only available in larger volumes (MOQ 5,000pcs).

......The mechanism available from stock in Denmark and our local partners is called CrushGrind Diamond.
We also have a mechanism range called CrushGrind Quadro, but this is only available FOB China and in larger volumes.
