Fifty is a bloody odd number
That's right in the sweet spot of annoyance - Too few for any kind of volume (real plastics, cheap parts and PCBs), and too many to casually knock out in an afternoon.
SLA plastics, then? Would help explain the grotty buttons - but the clear display cover looks like a real moulded part?
While it's no great loss if the Vega+ dies on its arse, it would be a shame for all the tooling to have been made, and then just a run of fifty cycles, then in to the bin. Especially for the people whose crowdfunding paid for the mould making.
£500K doesn't get you many goes round at design, tooling, testing. Does it look like they nearly got there, or is this a product that's 90% there, and just needs a second, and possibly third 90% to be adequate?
