This is an excellent value card - at 128GB for £30, what's not to like. Do remember of course that once formatted, as with any drive/storage, you won't get the full advertised capacity. This isn't a failing of this card or maker and in no way indicates a 'fake' card (unless you get just a fraction of the expected size), but just keep in this in mind. When formatted as FAT32 I got 117.3GB usable capacity from each of the two cards I purchased.

That said, there are a couple of points to explain why I docked it of one star:

1. As noted by another reviewer, the supplied SD adapters definitely have an issue. I have a USB 3.0 card reader with both a micro-SD and SD card slot. Plugged directly to the micro slot. both cards worked fine, but using either card in either adapter, I could not successfully format the cards. Try the same in another adapter I had lying around confirmed the supplied adapter as being at fault. As that's not why I purchased the card, I'm not fussed, but it could be an issue, and frankly why supply an adapter which doesn't work properly....

2. The maker is big on quoting the headline 80MB/s speed, but it's the write speed that really counts in the time consuming task of (for example) loading music files for a DAP or phone. It's 25MB/s here and in practice I saw around 12-15MB/s via a USB 3.0 reader and port. The more expensive Samsung and SanDisk SDXC cards will achieve around double these write speeds, so do keep this in mind of being able to load data TO the card quickly is a priority for you.

Overall then, a great value card which performs well, with just one lost star for a dodgy SD adapter and not really delivering on it's advertised write speeds in real-world usage.

The measuring was made in Windows 7 environment and does not reflect the real SD R/W speed.

Exellent performance and good price.
The tests with Android and real Samsung phone.

Card is unbranded so looks dodgy ... hence tested with hwtestw checks out for the size but the write speed is only 20Mbps - not advertised 40Mbps... Grudgingly keeping card as got it during amazon prime sale for 50% off, but disappointed it is not the speed advertised.

This came in easy to open packaging and I bought this to use with my Linx 1010b Windows tablet. This plugs straight in and I have had no issues transferring data on/off the device. The full capacity of the card is recognised with no issues.

A painfully slow write speed for me. Averaging 1 to 2mps. Once my music and photos are finally on the card I can test it in my tablet. If it's still woefully underperforming I will have to return it and buy a more expensive card. Very disappointing.

Works great with the Xperia Z2 (118 GB formatted capacity as expected). As long as the phone and/or card reader you are using is a recent product (i.e. was designed to accept large capacity cards) this will work.

I received this product today and mounted it in my Acer 10 Tablet. It loaded immediately, was ready formatted and recognised by the operating system (Android 5), which offered me the choice of using the internal or the new SD card as my default storage location..

It was a real breeze and couldn't have been easier. I am very happy with the purchase and definitely recommend this Micro SDXC card to anyone wanting to increase the memory on their tablet, cellphone or camera.

Bear in mind that, in common with all storage devices, the formatted capacity is slightly less than the unformatted capacity. In this case it was 117 GByte which is about right.

Excellent product. Just slotted into my music player and filled up with wav. files. No glitches or stutters despite the fact I have already stuffed it with music. No gripes about speed. Took time but got a steady 5 mps transfer speed. Very happy.
