Wellue Fingertip Saturation Batteries Non Bluetooth
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.
I double checked and the one I use is an old model (FL100) that appears to have been discontinued. The FL350 mostly resembles it, though it appears you are correct that the FL350 does not have an alarm. My apologies for the misdirection.
This one does have an alarm: https://www.amazon.com/Wellue-Fingertip-Saturation-Batteries...
