The SanDisk Ultra microSDXC 128GB memory card is a great option for consumers looking to maximize the storage capabilities of their Android or Windows phone or camera without having to compromise by juggling multiple cards or storage platforms.

Industry leading capacity point; Ten year warranty; Excellent build

Slower transfer speeds than most microSD memory cards

I bought this for my camera prior to going on vacation. We took almost 1,000 pictures and still had plenty of room left for many more. I highly recommend this product.

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.

Mounting/Visibility – Even though my phone (DROID Maxx) has OTG and I installed the Sandisk app BUT for some reason the drive would not mount it seemed. This is likely a ROM problem so I did not list it in CONS.

Portability – This is a very compact drive; It's not the most compact I've ever seen but it is small enough that it is as near as makes no difference; Versatility - Having both Micro and USB Standard-A ports makes this a very handy drive; Build - It is well built, not flimsy at all.

Compatibility – not all mobile devices have OTG capability Covers – The sliding covers do not cover the tips the they are easily pushed back making them not very protective Port Length – The ports are minimum length so if you have a case on your phone there is a good chance you will have to take it...

Very fast delivery...

Easy To Set Up; Easy To Use; Fast; High Capacity; Portable; Reliable

I have used SanDisk products before so it was a natural choice to seek out this one. The sandisk micro has never let me down. Works perfectly every time after many re formats. I like everything about this produce.

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
