Customers are saying

Customers frequently mention the Ultra Fit 128GB USB 3.1 Flash Drive's small size, ample storage, and fast transfer speeds as major advantages. The drive is also praised for its overall performance, ease of use, and large capacity. However, some customers have noted that the drive can overheat, and a few have expressed concerns about the plastic case material and its easily lost form factor.

    Great device, especially to leave in your laptop. Because it is so small it doesn’t protrude too far from the computer.

    This is a small profile memory stick. It is great for computers. Thought this would work with an airtv but does not seem to work. Regardless these memory sticks are always good to have. I did not give it 5 stars because I wonder of it’s durability overall.

    This thumb drive has 128GB, even bigger than my cellphone. It is perfect. The only short part is its size. It is so tiny, easy to loss.

    Great speeds, great brand (the SanDisk warranty/replacement program is pretty effective) - it runs a little on the warm side though.
