30pcs Mini Vibration Motors DC 3V Flat Coin Button-Type Vibrating Motor 10000rpm Self Adhesive Vibration Motor 10x2mm for DIY Mobile Cell Phone Pager Tablet Toys

These little motors worked great for making toothbrush robots with my cub scouts!

My son was doing a project for school and we used these. Function as expected.

The were ok. I used them to make BristleBots (toothbrush robots) with my class and they worked, but the ends of the wire are barely stripped so I had to strip them more myself. This was difficult because the wires are so very thin that they often broke or cut in the process. Luckily I bought enough to have plenty of extras.

The wires on the motors are short and very frail. I bought these for a STEM project and worried it’s not going to work. I ruined two motors trying to create my example because the wires broke off while trying to hook it up to the battery. If I am struggling with it I am sure my students will not have much luck getting them to work.

My students will love these for the many science projects we will do this year!

We used these to make bristle bots with our elementary robotics club. They did work, but about a quarter of them had a wire fall off. Thankfully we bought enough extra that everyone ended up with a working robot.

Worked very well for our project but they wires did not have much exposed wire so I needed to stip more, which with the tiny wires were tricky but doable. A few in this package didn't work as well as the others but over all, not too shaby! Especially for the price! I would definitely buy them again.

The wires are not pre-stripped and they are too delicate to strip without cutting them into. The adhesive on the back doesn't stick well to batteries.
