Ultra Fit USB 3.0 128 GB not detected

I bought this USB stick today but it is not detected by any of my devices. I have a desktop with Windows and Linux and a notebook with Linux. It is never detected. I even tried different ports. When I plug it in nothing happens and it is not listed in the device manager. Stick’s led keep blinking slowly. Is it faulty?

Have you tried putting it into a USB hub? I had mine die on me after 8 months and it would only be detected on a USB 2.0 hub. It would be best to return it, get your money back and buy another brand, like Corsair or Kingston. As most SanDisk drives heat up when in use and can actually burn you on some modles, like the UltraFit, and this is from experience.
