Review on Waterproof Mini Vibration Replacement by BestTong by Jeremy Carpenter

It was very good value for money. If you use them on R/C cars and planes, they are sealed, waterproof and the right size. I tried another brand but the wires weren't encapsulated in epoxy and my only concern was that if the wires came loose I'd have to take them apart to replace if the wire breaks or comes loose. The wires are long but very thin so make sure you have very small connectors and wires to connect them to your relays. One didn't work initially because I didn't have a good connection. Just for fun I tried 3.6V and 9.6V and both worked fine although I will only supply 1.5V. The 9.6V was on the PWM controller and worked correctly from 0 to 100%. I do NOT recommend exceeding the manufacturer recommended voltage. I just wanted to see if they could handle the stress. My next project is to make a wireless low battery indicator that will beep and vibrate for an airsoft gun so you don't run out of power halfway into battle.
