      Andriod Devices: Plug and use with built in app Called "My Files" (no need to install anything, unless you want to use other apps). IOS Device : Need to install a Third Party app called "iUSB Pro" (need to install a file transfer/managing apps, cause its not build for ios devices to use). And you need an Adapter that has a "Micro USB Female to Lightning Male Adapter ". This USB dual drive lasted me about a year. R.I.P Lever for the dual usb 05/21/2017 ~ 5/5/2018. The death of my lever was happened during me, who pressed too hard on the trigger lever that moves the usb to different modes, while it was stuck on a certain point where its not plug-able. Then I cracked it open with my keys, and was not able to put it back. I mean at least its still use-able, just kind of hard to unplug it. And its quite hot to touch without the plastic cover. It said its 64GB, but what I actually got was a 57.84GB. Also there is few files that runs inside the usb like .data + Android + LOST.DIR + System Volume Information. It might be just me, but just letting you know. I use this as a daily driver tbh, it might be because of that it broke in 1 year. I use Videoder alot with this product, since my wifi is slow af running at about 300 kbps average or less. In other places with fast wifi, I abused the crap out of the app for downloading mp3 and high resolution with 60 fps videos on youtube a youtube and some anime sites. Anyways its a good product for both Storage and File Transfers on Andriod Devices/Computers. Cons I have now, my raw usb heats up over time when plugged in too long, and it looks ugly with out the the cover. Pros I am happy with right now, it still works and functions just fine, and the time I bought it was only 20 bucks during black friday sales. Aside from the raw usb that heats up overtime, and the warrently that passed so long ago. It is worth the buy. Size : As big as a USD 25 cents.

      Great option to easily purge the phone's storage

      I bought this item because I have a 32 GB phone, and I was CONSTANTLY running out of storage space. Maybe half of it was apps, and the other half was media (pictures, videos, audio, etc). When I saw this item on sale, I thought it was the perfect opportunity to try its convenience. I was not disappointed. Here's a little pro/con on this item: Pro's: small (hence, portable), convenient, large capacity, sticks right in the phone to free up space, serves as another flash drive for the computer as well. Con's: You need to download Sandisk's App to move your files from the phone to the drive, and this is the one thing that I didn't like: the app itself. Very restrictive, not as user friendly as you would expect and while transferring files, the battery of the phone drains like crazy; so large transfers (say over 5 GB) aren't an option unless you have your phone fully charged. If you can live with that (I can...) then this device is a good option. The transfer rate is quite reasonable, so that helps in saving some time. But absolutely a much more convenient way to free up some space in your phone than plugging it in to your computer or deleting apps. Sure, you'll eventually have to stick the drive in your computer to free up its space, but that's way easier than doing it with the phone, and also a lot less frequent.

      Handy 2-way storage for the keychain...

      I already have plenty of flash drives - both "mini" and regular sized, but this tricked out flash drive has something that none of the other have: both a standard plug for the computer and a mini plug for the phone. Sharing phone photos or videos is now much easier, as you plug into a friend's phone, copy the pictures and/or videos to the flash drive, and then can transfer them to either a computer or another phone. The whole process also works going the other way! As soon as I saw this I thought of my friends who really don't know how to handle sending me multiple files or videos from their phones (other than posting them on social media) and this little gizmo solves the problem. Add to that the USB3 speed, and what's not to like? This has now gone on my key-ring (small enough for a lanyard as well) and is always handy when needed. When on sale, this is a very affordable "extra features" flash drive and is priced low enough not to have to worry too much about losing it

      Sooooooooooooo Slow

      I know that most will never test these out and will be happy with the performance because they will likely work with smaller files, so I wanted to share testing on larger files. Test A: WD My Book 5TB to WD Ultra 2TB (Both items were USB 3.0 and connected to USB 3.0 ports on the same PC) Result: 15GB file moved in 3 minutes (average write speeds of 65-100MBs) ---------------------------------------------------------------------------------------------- Test B (simply swapping this product in): WD My Book 5TB to SanDisk - Ultra Dual 64GB Micro USB/USB 3.0 Type A Flash Drive (Both items were USB 3.0 and connected to USB 3.0 ports on the same PC) Result: Same 15GB file moved in 18 minutes (average write speeds of 12-15MBs) Conclusion: This is my first experience with a USB 3.0 flash drive and I must say that I am very disappointed. I am not even sure how you call this a USB 3.0 device when speeds barely are above USB 2.0

      I bought this item since the Note 5 does not support external memory anymore. I was very excited to get it until I tried on my phone. Beware if you own an Otterbox case for your phone. The flash drive adapter is too wide and it will not be able to connect to the phone because of the Otterbox case. However I tried in a different phone and it works flawlessly. It's a great product but because of the main purpose was for my Note 5 unfortunately I have to return it. I highly recommend it but beware of it not fitting your phone because of your phone case. I don't own any more cases, so I can only tell you about the Otterbox.

      I bought this to transfer files from my Samsung S2 8.0 tablet, but when I got it and tried to plug it in, the case(Supcase unicorn beetle pro) did not allow it to fit in. I ended up getting a short male MICRO USB, to female USB type A adapter to make it work. Bottom line, it is fast, holds a lot of data, slide mechanisim is flimsy, the dual usb/micro usb is a good idea but needs work if you have a case. My advice, get the adapter so you can use any regular USB type A flash drive, and add more connection versatility to your device.

      Nice Concept But Not Pleased

      i got this because i needed to backup my phone which was maxed out (internal and sd) from thousands of pictures and a large amount of videos. everything started out fine until i kept getting a message letting me know it couldnt transfer items over. no matter what i tried, nothing would transfer. the thing was on sale and cheap for the storage amount. i shouldve stuck with my initial gut feeling and just got a 2nd sd card instead. i also just purchased a new laptop and wanted to wipe the flashdrive clean but that is even looking to be corrected by my computer. this is definitely not something i would recommend to anyone.

      very fast over usb 3. tons of space for the cost, best deal of all the different sizes. big enough to transfer several very large movie files and not have to split between multiple jump drives or use my gopro sd cards. very handy to be able to use on phone. much easier to transfer through drive vs plugging into computer if you don't always have a cable nearby or wanna transfer files without leaving phone plugged into computer. the drive is super small though. good for transporting, bad for handling. it's a little cumbersome to slide the button because it's so small. but not a deal breaker at all. i personally would've preferred it to be a little bigger and that function work better, since it'd still be plenty small to put anywhere.
