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

Just a little vibrator I used for a small 3D printer project. It seems to vibrate well for my purposes.

Good motors, nice long cables that are well connected to the motors and haven't broken off in my experience

Worked awesome for my need

Absolutely thrilled with this item. I made a life-size version of the board game “Operation” for an upcoming event and needed something to recreate the buzz felt when the sides of the walls are touched by the tongs. This was easy to work with, required minimal power (a simple battery pack worked great) and provided a great result!

Buen produ

OK, to start with the most useful information: if you find that some of these are stuck, try swiping a strong magnet across them. Almost all of mine worked once I did that. I'm guessing these have been in a warehouse for a long time, and the lubricant inside has gotten a little gummy. I also found that tapping on a table works, although I had to be a little more vigorous that way. The magnet method was one-and-done. So first off, QA. It's not great, but it's better than I expected. Out of twenty, I had one that straight up didn't work, and was able to get all of the others working. Five or six had to have the magnet trick, but worked fine after. The speed is pretty inconsistent from one motor to the next. I'll probably sit down and divide them into a "fast" and "slow" bucket. About four of them are in the "fast" category. The slower ones are still plenty usable, but if you're using several on the same project, you might want them to be consistent. The wires are extremely flimsy, so whatever you use these for, you're going to want to make sure you're not putting any strain there. I know this review sounds like all negatives, but these are 60 cents apiece. I was expecting three or four to be duds at that price. If you need a super strong, consistent vibration motor, this isn't what you want. If you want something cheap and tiny to provide some crude haptic feedback, these seem totally fine.

I am thoroughly shocked, these items (while given still in the anti static bag), when through the washer and the subsequent dryer trip, and still work as intended, I find this impressive.

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

Nice product but the cables break quickly.

These are not the motors needed for the bristlebot STEM activity with elementary school students lol (using a 3V battery). They don’t vibrate enough to cause movement that is interesting/exciting. Good product overall I guess, but I wanted to warn other teachers who might make the same mistake.

I'd like a refund or send me more of these motors. I ordered a pack of 20 and that pack of 20 came with 5 motors in it. Missing 15 motors.
