Powerful 10pcs 6x14mm Micro Vibration Motor 1.5V-4.5V 0.195A 19000RPM Strong Vibration

All of the motors worked as they should. The wires are a bit thin but I reinforced them with a spot of epoxy so they will not pull out.

They were good little motors and vibrated well - my only complaint is that there wasn’t enough bare copper at the end of the wires, and the wires were so small they were hard to strip further.

First 20 worked fine but I ordered 30 and the diameter is wrong 4mm not 6mm. My 3d printed platform will not work!

I have mixed feelings about these motors, but they're powerful when they work. Several of the motors had the wires missing right out of the box. The wires are so thin and difficult to work with and have inconsistent lengths. Before starting any projects I apply hot glue to the base to help secure the wires. Then I test the motors before starting. Even being careful I've found several times the motor is no longer working by the time I've finished my project. The manufacture should have used a larger gauge wire and secured it to the motor better. It has been time consuming and a waste of materials. If you just put the wires on the battery it's a pretty weak vibration, but when used with a variable speed switch It's impressive.

I bought these to make doodle bots with my Girl Scout Troop. They worked perfectly. I had read in other reviews about the wires pulling out easily so I put a dab of hot glue on the end where the wires connected before using them and we had no problems. My girls were very impressed.

The vibration motors worked fine except for a few. The wires are only stripped about 2-3 mm and that isn't enough for children to work with. The wires are extremely thin and stripping them more is difficult. Also, the thin wire pulled out of one.

Pretty nice little guys.For sure drop a glob of hotglue on the wireleads to strain relief them before anything because they're pretty fragile.Haven't run them too hard yet but I'll update this if anything new becomes not worthy.5V pulls ~600mAh btw

most of them did not work or stopped working after a few minutes, which made for very disappointed kids who were trying to make bristle bots with these.
