Product reviewsSanDisk Extreme 128GB microSDXC Class 10 Memory Card with SD Adapter

Thank you.

Really good product. All the gigabytes are there. I've tested 2 of 3 cards that I bought. One on my PC other on my phone. PC results
"Warning: Only 121441 of 121910 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 20.5 MByte/s
Reading speed: 37.0 MByte/s
H2testw v1.4"
The warning is because I've saved few files before the test and didn't delete them.
The slow reading speed is because of my card reader it simply can't do it faster no matter what card I use.Read full review...

Possibly not a genuine SanDisk

This card keeps failing, then it crashes my mac, then it keeps popping up with read error when it's in my dash cam, so tried putting music on it as to just test it, well you can guess, it crashed and then something weird happened, it lost half of its memory, i eventually managed to reset it and after a few weeks all the errors that ive mentioned all began to happen again, i thing its been upgraded to 128GB and i really feel its may not be a genuine SanDisk item, i may be wrong but i doubt itRead full review...

Good price for the size

Arrived on time genuine product works well at this time no issues with card.
The only issue is with the manufactures of all cards they do not give extra memory on the card to cover the 10% approximate loss for formatting so you get a full 128g of usage.
On this card 119g usage availableRead full review...

Genuine Sandisk 128GB micro SD card from basecomshop.

Purchased this 128 GB Sandisk micro SD card from basecomshop, got read / write speeds of 84MB/s and 69MB/s using h2testw through my card reader with no errors, so these seem to be genuine cards.

This one works!

I've used other SDXC memory cards as additional internal memory & had some issues with speed / timing out - this one is a bit quicker & works a treat on my tablet.

Value for money.

A good high speed memory card with plenty of storage space (128Gb) & Sandisk quality at not a high price.

Good value, Good quality.

Genuine SanDisk card. Works perfectly.
Fast Read & Write speeds.
Got this for my Dash Cam (Dual, Front & Rear), and it works well.

The speed you need

If you transfer many files across pcs, phones, etc. or you shoot 4k videos this would the only option. I have this Extreme one at 160 MB/s and the Ultra one at 100 MB/s and the Extreme is at least 3x faster.Read full review...

Exellent product

Arrived very quickly and works great so far. Fast transfer speeds and about 120gb of space it seems.
