Well that's probably what they'll end up doing
Get people to send them in for a replacement
How else could they do it?
Like I said earlier, if I do get a set, I'll likely just keep it rather than send it it because if most do send them back the error ones will become rare, and as a collector of things, that's kind of cool
I never use them so I could really care less.
I have the proximity mines and that's what I usually use anyway.
Cluster sucks in comparison imo
