No replacement cups
The first cup broke after just a few months (those little tabs on the cup are very fragile and will break one after another until the cup become good to nothing).
I moved to the second one and the extra tall cup to prepare our morning blasts. When another one surrendered, I looked every where for replacement cups and could not find them anywhere. Some are available on eBay for prohibitive prices.
If the big idea behind this is to push people to buy an entire new equipment so be it. But I will definitely move to the completion and investigate carefully about their options for replacing parts.
