I bought one of the cheap ebay listed cards and installed it in our 2020 GT. I made sure to buy it from a seller with a well established ebay reputation. It has Mazda labeling and was manufactured a couple of years ago. It updated correctly and performs perfectly. If it is a clone, it seems to work just like an original. The labeling looks authentic. The Mazda update system accepted it. The car accepted it. The Mazda site indicated that when I updated it, that started the 3 year clock. Have read plenty of online testimonials that concur with my experience.If my memory serves me right, it locks in after 50-60 miles driving with the sd card in for the first time. Then the period starts.
The problem I see is those cheap ebay listings are probably clones and they are with the release map year of the master card. No idea how it works with them for updating.
Have read a few online posts that speculate about possible performance issues with ebay sold cards, but don't remember reading any posts written by someone who actually bought one and had a problem with it.
