Isn't aluminium better for longevity/reliability?
But I have a plastic VR headset and I'm pretty sure an impact bad enough to damage the plastic care is also bad enough to damage the electronics, which are going to be way more costly to repair.
I'd take a plastic headset personally assuming it was lighter. Anything to save weight in this product category.
It's not even scratched. I have no idea what it's made out of but it's super impressive. I try not to think about because of whatever the biosafety standards were back then... but the lack of visible damage gives me hope not much of it has been ingested at least.
