Why is this suspicious? I'm curious, as it just seems to be a promotion of sorts.
They have been offering promotions for both, "batches", but I have yet to see anyone post that they have bought a unit or received a unit, despite claims that the first batch has been sold out, and this one is almost sold out.
It sounds like they are saying batches are almost sold out to make it sound like a, "Last Chance" type of deal, get yours before they are gone, but there really is no proof that these exist, and no one claiming they do from the previous batch.
Also, they apparently refuse to get them reviewed, which would only cost them one unit, but instead are able to offer a 50% discount on 5 units, which would be equivalent of 2.5 units being given away, when, once a verified member reports these as real, they shouldn't have a problem selling them at full price.
These things lead me to call them suspicious.
