Verdict: 3/5

20240330 One more point deducted due to the recent frequent wireless (USB dongle) performance issue. Bluetooth seems fine.

202403 Would have been 5/5, but I had to deduct one full point due to recent degraded wireless (USB dongle) performance for unknown reasons.

After purchase

Touch typing

Settings shortcuts

• Power switch (second one from top right)

  • OFF: right-most position
  • Wired: middle position
  • Wireless (using USB dongle): left-most position

• Win/Mac switch (top right)

  • Mac: left
  • Win: right
  • 🤷 Quirkiness: Ironically, setting it to Mac will enable F3 for 'next hit' after the toggle, but setting it to Win will not work. ( #todo verify this is still the case)

• Battery level: FN + \ Green indicates a high/full level (Beware: the battery level is shown only when the charging cable is unplugged.)

• Indicator lights (both sides): FN + / + up/down arrow

• RGB multicolor lights/glow/flashing: FN + H (Halo) + up/down arrow

For use by the Windows 11 Pro VM

• Use OPT (option) key for ALT on Windows, naturally
  • e.g. CTRL-OPT-DEL to effect the "three-finger salute"
• Use CTRL (or sometimes CTRL-CMD) to effect the CTRL key on Windows
  • e.g. CTRL-R (or CTRL-CMD-R) to start OCR on selected pages in FineReader
• Use F1-F12 function keys like normal, e.g. F5 for refresh, F3 for next hit
  • Toggle FN-TAB-'F' (the letter 'F')

Issues

202404 The difficulty in getting after service revealed that Nuphy is a company based in China. And, its firmware upgrade requires a Windows machine: there's no way to upgrade the firmware on a Mac or through a Windows virtual machine. I wish I had known this before the purchase.

202403 Soon after I came home from the Taiwan trip and reconnected all the USB hubs including setting up the newly purchased 7-port USB 3.0 to USB Type C adapter, the Nuphy Air75 wireless connection, which used to be fast and smooth, started to become iffy--it was either slow, unstable, or skipping or adding letters. Very annoying. I had to resort to using the wired option (thank goodness it is an option) almost always now. Very disappointed! It's strange this problem coincided with the failure of the old 7-port hub and the addition of the new one.
