I bought 33 tags/cards from multiple vendors on Taobao/AliExpress and tested them one by one.
Most of them simply reply SAK=08 even if you changed SAK bytes.
Only 4 exceptions (2CUIDs, 2UIDs) implement real SAK change. Therefore, I immediately placed a larger order to build a reserve of this type of "precious" fully changeable tags.
They are on the way, I haven't tested them and remain pessimistically optimistic, since sources of these chips are mixed and unstable.
Willing to trade with anyone who need UID or CUID with such changeable SAK.
I am also willing to exchange these tags for any versions of secondhand Chameleon.
