Tested this out with inbuilt card reader of a laptop, around 10mbs write and 20mbs read, not the 30/30 stated but better than usb flash drives

This card is excellent for expanding storage on your smartphone. Its transfer speeds are are very fast hence it wouldn't slow your phone down. Only down side is that it is a bit on the expensive side.

The 128 gb MicroSD card will probably work OK in cameras that support the SDXC standard, but I reformatted mine to Fat32 and carry about 75 gb of data on each card as backups that can be carried in an ordinary wallet.

Can Be Carried In Wallets; Extreme Small Size

Not For Computer Backups

Very fast delivery...

Beware - the micro SD shown here is UHS 1 with U1 symbol, but I was shipped a C10, I have raised a compliant with infibeam - haven't been resolved yet.

The price was the first thing I looked at. The quality was the same as others I have bought from other suppliers. I am happy and would buy from this supplier again.

Great brand. Great price. Just what the phone needed no formatting no compatibility issues just insert ant go. Would not buy any other and at this price wouldn't buy from anywhere else

The memory card itself appears to work fine. I'm using it in a GPS to expand the memory so that I can get the full map of the United States as well as Mexico and Canada. I was very surprised at how small the item itself was and wasn't even sure if it would work properly in the GPS.

I bought this 16GB microSDHC card to increase the storage capacity of my SanDisk 4GB MP3 player. 4GB is just not enough for all my tunes! It has worked just fine with no problems whatsoever. Note that this is a Class 2 card, i.e. on the lower end of cards in terms of speed.

I got this so that I can have more memory on my phone for music and movies. Also it I can easily put the sd card into the adapter and use to transfer images and videos to my laptop.

Easy To Use; Lightweight; Reliable
