I measured about 150 MB/s, which roughly corresponds to the level of my PC. See attached results. The theoretical speed for USB 3 is 600 Mbit/s. A flashing light indicates activity. There is no size marking on the case, but there is an engraved marking on the metal USB connector. significant feeling. It has a small plastic grommet to add a lanyard, but it's flimsy. I barely pressed it with my finger and it broke. The $17 price seems right, about the same as other flash drives with these specs.
