20PCS 10mmx3mm Mini Vibration Motors DC 3V 12000rpm Flat Coin Button-Type Micro DC Vibrating Motor for Mobile Cell Phone Pager Tablet Household Appliances

We used these to build robots with our wolf scouts. We all loved and they were easy to use. Definitely would buy again

Cool little buzzers!

These little guys are fantastic. They vibrate like crazy.As soon as I got them, I just put 5V through one. It only drew about 100mA and was incredibly potent.I bought these for fun...and now I will probably need more because I'm totally goofing with them and making 'gifts' for friends.

I used these to make a VR haptic suit, and they work well! My only complaint would be that the soldering is weak, but then again, these probably aren't made for clothing and constant movement. If you plan to use these on something with a lot of movement, a dab of hot glue on the soldering points will make it significantly stronger.

I used 1v, 2v, 3v, 4v and 5v. Worked fine on all of them. They were quite strong and powerful for their size, approx 3/8 inch diameter.

They work like they are intented to!I made a project with arduino + vibration + UDP broadcast to make a vibration bracelet to give anonymous feedback to deaf actors during a theatre show.No problems. Easy. The vibration strentgh do depend on the voltage. I have tried 3,3v - 12v. Good!

These worked great for our bristle bots we assembled in Cloverbuds!

Bought for a cub scout stem project. We used the motors to make bristle bots at a pack meeting. Great value for the money, our whole pack was able to make them
