The reason they’re fine is because this is a really niche audience who generally know what they’re doing. The few occasions things do go wrong, it’s almost always the fault of the person the bought it, and we accept that.

Those that do want something like this and who isn’t a hacker themselves would go via a 3rd party to mod it, usually paying them too (That scene is also massive in the EU).

The very few times I’ve had to return something has been simple enough. Full refund for an item that is either dead on arrival or they person just sent out the wrong item accidentally. Either way, we are talking same week rather than 2 years later.
