8pcs 10000RPM Mini Tiny Vibration Motor Wired mini Flat Pager Electronic Mobile Phone Coin Cell Splice Flat Coin Button-Type Vibrating Motor

Precision made, great for any handheld device where you don't feel like listening to a loud buzzer for call.I'm using these on some Lilygo T-Decks (Text message via LoRa, Long Range Signal).I liked these since they don't take up any room, but vibration level is good for such a small footprint.Wires are small, but no doubt properly rated for use.I would recommend these for any handheld project where you want an vibration type alert but don't have much space onboard.

Be aware that these are itty bitty things. I’d have loved to strip the ends of the wire back but every attempt just snapped the wire off completely.
