Customer Ratings & Reviews

Great for every day carry. It has a unique design which allows you to use either on a desktop or mobile device. Only issue is when inserting either type of port into the device or cpu the mechanism that is supposed to go in seems to slide right back into its casing. So you kind of have to hold it a certain way for it to go in properly. Nothing major but can get frustrating at times.

I have been using the 64GB version for the last year and have had excellent results with no data loss. I bought the 128 GB version for additional storage on my Samsung Galaxy S-6 Edge phone, which recognizes both 64GB and 128 GB versions of this drive. Outstanding buy!

Very portable flash drive to store plenty of files and pictures. The versatility of fitting in a phone and laptop.

Pro: Dual connection, great for both PCs, phones, and tablets. Con: The drive heats up quickly.

For those needing a flash drive for your micro USB-abled smart phone, this little gadget works great. One side has the standard USB for your computer, and then when you store all you need, slide the micro USB for your phone or tablet. Just pop it in, and instructions come up showing you how to open the folder. You can work with it while the flash drive is attached, but I don't recommend it as the connection is a little loose. It's better to copy or move the file, MP3, video, etc to your device. HIGHLY RECOMMENDED!!!

Great for downloading my pictures from my samsung phone and tablet, I can see them on my tv screen and take this drive to have pictures made for family, Wonderful idea.

Excellent storage device except for the fact that it heats up rather quickly while in use.

great capacity, good speed and small. If you are prone to losing things, maybe too small

I purchased the Sandisk - Ultra Dual 128gb Micro Usb/usb 3.0 Type A Flash Drive - Black as a sure way to quickly back up my SmartPhone data, pictures, and contacts. It is easy to use and works perfectly. Depending on the SmartPhone you are using, mounting this device might take some research on your manufacturer's website, but this device should work on all SmartPhones.

I purchased the "SanDisk - Ultra Dual 128GB Micro USB/USB 3.0 Type A Flash Drive - Black" to be able to backup all of the data on my phone. It has both the micro and standard USB interfaces (one on each side). Both my Samsung Note 5 and my computer recognize the device. It's also nice to have one of these to off-load any pictures from your phone when you need to do so. It's very small and does not take up much pocket room.

I love these dual use devices. I transfer files from computer to phone, and even store music on them and play directly from the drive through my phone. I received 4 8GB a while back. Constantly switching was annoying. This has now replaced all of those.

If you are looking for a large capacity flash drive and want a small physical size, this is the one. dual USB connectors make it easy to transfer from pc to phone.

Love that I can back up all my music, photos, and videos to the SanDisc as well as being able to back up my computer. Small enough to travel with in case of needing to back up phone documents. Love it!

Fast flash drive with both USB 3 and OTG feature. File transfer is fast between systems and reasonable price for such a high capacity.

I really like my new sandisk usb as i am able to transfer files fr my computer and watch it on my smart phone!

I like the size of this Sand Disk flash drive. The speed is real fast and is very practical the dual connectors. I really enjoy it.

Handy flash drive with lots of memory. Dependable storage and easy to use and carry.

Sandisk, if you guys actually read this stuff, I just wanted to thanks for making this product. I was able to save all my photos on my failing phone. Saved some precious photos. Thank you guys!

Ease to use. Perfect size. I would recommend to anyone looking for a flash drive.

Affordable Flash drive for backups of Android phones with Micro USB - B power adapter port and especially ones lacking micro sd card slots. Since it it dual type USB, the files can be transferred conveniently between you phone and PC on fly. Moreover it has secure vault to encrypt the data on it.
