bad SD cards

I hear typically the SD cards ship with anbernic are trash and fail fairly often.

If I buy the device it includes 1 card and I can also buy an additional card which I will do for more games.

Do you reccomend buying a new SD card or 2 new cards and cloning it

Do both these cards typically fail or just the one with the OS —-that just a rumor ? Or they work fine ? new to this so any help appreciated !
