Hey @Friedrich
We understand the demand for more spare parts, but it has been improving incredibly hard to source more of them. I won’t go into more detail here, for more info check out this blog. What I just want to say is that we might indeed have underestimated how hard it is to source these parts when we (more or less naively) started out with a couple of people back in '13, but we are trying so hard to make this happen. We are as frustrated as you guys are, but believe me… it is not for a lack of trying from our side.
In any case, FP1 batteries are back in stock and we have more FP1 displays coming later this week.
