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...

i like it for what I do the USB connector retracts so that it is protected without having a separate cap to get lost or miss placed and it has a loop on the end so I can put a lanyard on it or connect to a keyring.

Wonderful deal in great price! Data transfer rate is very high. Indeed, a great product by Sandisk!

Backup storage and Transporting of documents

I loaded a number of files on the flash drive and the first time that I tried to review the files, I could not access the drive, then could not even erase and reformat the drive. Costco's return policy has been great.

The flash drive has a slow write speed despite the available and fully functioning USB 3.0 port on my neighbors desktopPC. I am currently transferring 20 GB of data, without any increase to the expected 40 mb/s speeds as advertised. Reasons?

This flash drive boasts "up to 4 times faster than USB 2.0" speed, but what they don't tell you, is that it only means the 'READ' speed! This thing is not ONE BIT faster on WRITE (copying files TO the device!) than any USB 2.0 device when using a USB 3.0 enabled plug.

not excessively expensive; (less than 14 dollars

very slow write speed even with usb 3.0

Sandisk Ultra Dual pendrive is a 'must have' item for smart media storage management ....Unique product with smart concept...!!

Picked this up a while ago. It's been with me ever since. This has got to be the best USB stick I've ever had, it won't win any awards for transfer speeds, but it won't let you down either. I mainly use this for storing films & tv series which I watch at work, either on the PC or on my phone.

A small device for availing many facilities: Pros:- SanDisk develops and engineers its USB Flash Drives to maximise reliability, so you can count on your USB 3.0 Flash Drive to store your important files.
