I did not see any difference in my recent add-ons but they were only a year apart.Tried to use the search to find the answer to this but wasn’t finding the answer I was looking for. For those of you that have done add on orders and gotten more quantity of the exact chip you had ordered in the past, can you tell any difference between the batches once the chips are in play? Trying to decide if my OCD will be able to handle if you can see a slight color difference if anything like that is noticeable.
