Customers are saying

Customers are positive about the Ultra Dual Drive Go 256GB USB Type-A/USB Type-C Flash Drive's generous storage capacity and ease of use. Many appreciate its overall performance, small size, fast speeds, and dual connectivity for use with both mobile devices and laptops.

    It fits my needs and I like the dual ends so that the flash drive is accessible to my new MacBook as well as with other computers. The only thing is is that it feels lightweight and I get nervous every time I take it out of my computer, because I’m worried it will break. Other than that, it was a good price, has a lot of storage space, and works well.

    I like that it has multiple USB ports as the world transitions to (but is not yet at) USB-C universal use. One draw back is it doesn’t have as much storage as advertised. But considering I bought it on sale, and the dual port feature, I’m not heartbroken about it.
