To me, I'll take it at the
GOL's word that they obtained the latest unit.
I would imagine that giving the receipt date/serial number could well allow tracking of WHO purchased the unit, thereby exposing their blind-purchase source, a loss which cannot be easily recovered, and would be akin to a media outlet violating its trust with confidential informers.
I understand that this leaves a lot to be questioned, particularly of the conflicting data between the observed performance of the tested unit versus the XR and what the engineers at LaserMask are saying, but I think that with all due consideration, it's perhaps the best resolution that we can come to.
With that said, I think it's also important to point out to any stateside who are considering the LaserMask that the XR performance is irrelevant, as it is very, very, very unlikely that we'd ever face this threat, in North America, much less in the USA.
In my mind, even the tested version of the LaserMask - even if it is not the latest revision - is more than good enough, for those searching for something that's "good enough."
