We're switching to solid vinyl as the material for our portafilter handles. We like the way they feel, look and wear.
However, in torture testing our first batch of 20, we found that we could break the top off. This was because the bolt connecting to the stainless steel head, wasn't that deeply sunk into the vinyl material.
We've remade 20 samples, now with much deeper bolts sunk in, and we've not yet been able to break one.
The solid black vinyl will be the new standard in the future, that comes with our black machines.
So... now onto manufacturing these!
