15PCS 10mmx2mm Mini Tiny Vibration Motors 10000rpm Flat Coin Button-Type Micro DC Vibrating Motor for Tablet Pager Mobile Cell Phone

These have pretty strong vibration and they stick well

I ordered these to use to make noise in an alarm to scare squirrels from a bird feeder. Placed in a small plastic pill bottle, when activated by a PIR, it made a substantial enough noise to send the critters running. The alarm also worked for racoons and deer, but the alarm was retired to make way for a more "professional" unit. Shipping was quick and all received were tested and all worked.It is not a flaw by any means, but the wires are very small, and care must be taken when cutting insulation or soldering. Otherwise, they worked great for the project.

While it works well enough, the included mounting adhesive is not good enough for more than a couple hours without extra support pinning it in place.

I bought 15 of these for a project for with classmates in my master's program. We ended up creating 3 prototypes of our design and all vibration motors worked effectively at a low cost. The only negative I saw was how thin the wires were. However, despite that they still worked for us. I am not sure how long they will last, but for our needs they were perfect.

The motors work consistently and are great for adding haptic feedback to Raspberry Pi projects.

Every single one works perfectly, and they are much stronger than I had expected, considering their size. The voltage and power requirements are low enough that they can be driven directly by logic level PWM outputs of common microcontrollers without any problems or loss of performance.

Bought these to serve as a thinner (and far cheaper) alternative to ones bought from da "fruity" reseller. These are pretty much as expected. Thinner. Perhaps slightly weaker in terms of "buzz." But all I've tried are working fine. The wires are slightly longer and thicker gauge. Overall I definitely like them and would purchase them again. Recommended.
