Look at the link it shows £128.99 and from £45 used from other sellers all three show as just launched oO

No way should anyone consider anything but Amazon themselves or a reputable Firm, I get your point

​Yep, I wouldn't go near any of the other suppliers with a barge pole!

As already mentioned H2TestW is the way to go about it. Set it to write and verify then leave it do it's thing for the rest of the day as it's going to take a considerable amount of time to write 256gb of data and then verify it all.

I would install an app called SD Insight from the app store first (20 seconds to install and run) then if your still in doubt run H2TestW (I used to do but don't bother now).
