On my pictures here there is a clearly visible oval shaped spot with a parallel scratches, like that area was scraped with abrasive. Rest of the cell surface is even and smooth. I didn't remove the glue, just ripped off the black cover.
On Ray's video you can also see that under the glue area around QR code is different. I am talking about bigger spot, not just the small square which is also looking odd.
But of course to properly check the code on his cells it would be better to remove the glue and look at the code area from different sides with proper lighting angles.
PS. Found a year old thread
RayfromTX Gone..? Huh..? on this forum.
Will Prowse banned Ray for pushing Docan here to forum members.
It is the same Ray that builds cool stuff

I receive a commission on sales from Jenny Wu when my youtube channel is mentioned at the time of contact. I don't have an affiliate link. I try hard to not self promote. In the case of the post that got me banned, I was responding to someone that was having a hard time with a payment method so I posted Jenny's email address so she could sort it out and get the discussion off the forum. Many people come here to find this information. I don't sell anything and technically, I have no affiliate links here or on youtube. My income comes from working in construction. I have turned down many offers to promote companies on my youtube channel but I prefer to not go that route.
My Youtube channel is Ray Builds Cool Stuff."
Will perfectly handled that situation, can't agree more.
