    Not much to say about this flash drive other than it works well and has fast transfer speeds. Large capacity drive makes it possible to store/transfer very large files that you simply can't do with smaller capacity drives. Small form factor is good, but can also make it easier to lose, so be careful with it. Only knock I have on it is the casing being all plastic, which isn't as durable as metal.

    I don't use the 'cloud' and I don't use the hard drive on my laptop to store my files. I have several SanDisk 128GB USB flash drives. I prefer SanDisk drives in this compact format because they are fast and do not heat up during use.

    Great Low Profile Flash Drive

    This is a great flash drive with a low profile that works well if you need to leave it connected to a device. I have it connected to my PS4 and it works great to add some extra storage without having to use a large external drive.

    Honey I Shrunk The Flash Drive!

    Dang this thing is tiny. It is a very convenient small form factor USB flash drive. The biggest advantage is being able to leave them in your device. The Ultra-Fit extends out about 1/4" when plugged into a laptop (or other device with a USB 2.0, 3.0 or 3.1 port) so you can leave it plugged in all the time. The only down side I can think of is also due to its really small size it could be easily misplaced. I would suggest if you are taking it in and out of a device that you put some sort of "leash" on it. There is a small loop on the outer most edge that would accommodate a tether of some sort. Now if Sandisk could just incorporate a universal mouse receiver like a Logitech nano then it would be really cool!

    Use this for general storage as well as for music in my car. You can plug it in and forget about it. And you just might since it is SO TINY! 128GB is plenty of storage for music or photos.. It is a great multi purpose drive. The only drawback being it feels very flimsy and cheap. However I have not had it break yet.

    Decent usb thumb drive

    This has plenty of atorage for anything youd like to swap over to another pc, or use as extra space on something like a sSield TV box. My one and biggest complaint is the insertable body is a flimsy plastic material. Where other Sandisk usb drives I own of smaller storage are metal. The included cloud software works good after downloading it to your pc, Im nlt a big user of cloud storage. Nut, all in all thks version by Sandisk works and is easy to use to backup your files. No problems using thks drive to swap over pics and files from my desktop to laptop pcs. Other than the plastic body I would reccommend this to anyone needing affordable thumb drive options.

    I like this flash drive. It works great especially in my laptop. I was transferring files from my desktop. Just remember that it's not fast if you aren't using a 3.0 port. It took a while to get data on the drive because of that but hooking it up to the faster port dumped the data very quickly. SanDisk offers a service with this drive that backs data up to the cloud in case you lose the flash drive. Seems nice but when I was using it it took forever for the drive to back up. It just didn't seem to be worth it since this drive won't be hooked up to a port very long for effective backup. Beyond that service this is a great product.

    I bought the SanDisk to load photos for friends who lost pictures in the Marshall fires. It was easy to do, and I’m assuming the recipients had no trouble seeing them on their computers. The ScanDisk satisfactorily filled the need for which it was purchased.

    The SanDisk Ultra Fit 128 gb usb 3.1 Flash Drive is really small. There are thumb drives, but this drive is smaller than my thumbnail. It has a big capacity for a removable flash drive allowing me to store lots of files. It also comes with free cloud storage for backup of the data you put on it.

    At first glance, this looks like many other similar flash drives. But it's not only fast, it also offers secure access backup - which encrypts the data. Overall a solid offering.

    This flash drive has plenty of memory. I downloaded over a hundred high resolution pictures and only used 1GB. This flash drive comes with FLASHBACK free cloud storage for a year. Directions are included in the package. Follow instructions to download app. Close app, plug in the SanDisk Ultra Fit flash drive and Flashback will backup all data on the SanDisk. Only gave 4 stars, because it took a while to set up the FlashBack cloud storage correctly.
