Yeah, warranty returns are less than ideal as in a worse case scenario, your data has already gone up in smoke which no new card can compensate for. And even when you do send it back, you potentially have some tech head at Sandisk having access to your photos, and whatever other personal data you have on the card.

You are right. I have trouble formatting the 64gb in phone, tablet and windows 10 pc. Two cards 32gb and 64gb failed on me last week, not recognized anymore in any phone, tablet or pc, and were a replacemenet from Sandisk, so Im not bothered sending them again as I lost trust in the brand, so will probably a Toshiba one. Hopefully, they are more reliable.

As an aside, every comment I make lately 'is flagged for moderation'. Any advice on how to fix this please? (using android app on tablet).

Can I use this with an adaptor in the bigger sized sd slot in my car?

I picked up the 128gb version for £17.30 at Tesco Sunbury so looks like they are clearing stock but they didn't have any of the other sizes

Went to Sainsburys today for some groceries and saw this reduced from £15 to £10, put one in my trolley, scanned at £12 and then reduced it by £4.01, Happy now:-)

The biggest issue that I have with the Sandisk Ultra cards is their unreliability. My one failed after only 18 months and locked itself into read only mode. No amount of attempted formats or using SD utilities would fix it. The Extreme and Extreme Pro lines are apparently more reliable.

will this fit gopro?

64gb out of stock

32gb for £6 from sainsburys

Brought the 64gb one this morning as was in desperate need of extra storage on my phone, u get an extra 40 clubcard points with these cards aswell.

Buy Class 10 u3 not this...
