    As every SanDisk product, it is reliable and holds quite a bit of data. I also like the physical size of the unit, it is so small that you can barely see it.

    This SanDisk - Ultra Fi 128GB is small, fit easily in my pocket, and holds so many photos, music and movies. The downside is that it hits up when writing on it, and the speed is limited to 10 MB per second.

    This flash drive from SanDisk offers no surprises - and that is a good thing! It reliably holds a lot of data in a small form factor. Data transfer rates are consistent with the USB 3.1 standard and the item is very unobtrusive when left plugged into the USB port in my car.

    I like to use flash drives for additional backup and portabililty. I particularly like this small format because it fits inside my eyeglass case. It also seems less vulnerable to accidental damage because it protrudes very little from the edge of the device it's plugged into. Comes with password protected "vault" so files and folders cannot be read by anyone even if the drive is lost. Pretty easy to drag files back and forth between computer and flash drive. I got three of these and rotate them as backups that I keep in different locations -- again with ease of mind because all of the data are encrypted. Doesn't have the LED indicator that I like on other flash drives that signals read/write.

    “The SanDisk Ultra Fit 128 GB USB 3.1 flash drive strikes the perfect balance between ultra‑compact design and impressive real‑world performance.

    This thing barely sticks out of the computer or car, which is good. Don't want somebody to bump it and knock it loose. Great storage capacity and transfer speeds are very fast.

    This is my 4th purchase of this product. Its fast and efficient although, I wish it were not made of all plastic. Worried about it heating up and melting. But other than that, I am very pleased with it.
