SanDisk Extreme 256GB - 0 Spare Blocks Remaining in CrystalDisk

Hello,

I’ve bought a SanDisk Extreme 256GB USB stick from ebay and checked it with CrystalDisk:

Can someone confirm that the report means that I need it to return it as defective, as I don’t really understand the results but 100% Bad doesn’t feel good.

As well as the “E8 Spare Blocks Remaining” = 0, if I hover over the “Bad 100%” in Health Status it also mentions that “E6 Percent of Total Write/Erase Count” - 100 is bad as well (even though it’s not highlighted in red in the list itself.

All advice gratefully received.

Thanks.
