Pleasantly surprised at speed of delivery, order arrived the following day. Build quality seems sturdy and comfortable, although the drive is even smaller than I expected. Sequential read speed is even better than advertised when plugged into PC via USB-A (155 MB/s vs 150 MB/s, although sequential write speed is a more modest 40 MB/s. Strangely when connected to my phone via USB-C, speeds are far slower: 40 MB/s read and 20 MB/s write. I would have expected USB-C to be faster, but nevertheless it's still acceptable for my needs. Overall extremely happy with this purchase.
