BOJACK N20 DC Vibration Motor 2PCS 3V 8000RPM Powerful Small Electric Motor Micro Vibrating Motor

They are small vibrating motors. I used them to make a vibrating table for resin molds. They work.

I bought these to replace a large vibe motor in a plush foot messager. I wired 2 motors in parallel, one for each foot. Not only do they message stronger than the single motor, but the batteries last much longer, so these are far more efficient. I thought I might have to wire them in series to reduce the current, so I was really surprised they worked better, while drawing less current . I was planning on using a piece of PVC pipe to isolate the weight, but found the inside diameter of PVC is larger than it is marked. I ended up using a thick piece of heat shrink tubing around the front of the motors to guard the weights.

good stuff, make sure during use these are ventilated, I had one die pretty fast... the second one I have used is lasting way longer... so I still have 3 in the bag. good vibration for size.

Worked as expected. More voltage, more vibration; less voltage less vibration.

they work but too small

These are just as described a good value

I purchased this item to be attached to a small parts gravity feed chute that sometimes needs a shaking to get the parts moving. It works fine in combination with the multi-voltage speed control purchased also. Does require soldering of wire with a low wattage soldering iron typically use on electronic devises. Note that there are no hard attachment points. The devise will either be clamped as I did using tie raps or other clamping means. Possibly it could be embedded in a material that cures from semi liquid state to a firmer or even hard state. Your decision on fastening for use.

I made a finger vibrator. Its small enough to be unobtrusive but has good vibration.
