4 Sets TT Motor DC 3-6V Gearbox Motor Dual Shaft 200RPM Ratio 1:48 Motor with Tire Wheel Kit for Arduino DIY Smart Car Robot

I used them to make a robot car.

Great product! I use it with Arduino with a motor driver board.

I ordered these to build a turntable for a photography light-box. We only needed one and it worked perfectly. Even so, it is good to have spares on-hand

All four motors worked so it's all good. The included wheels are actually good quality, especially if one doesn't feel like converting the 3d printer to print flexible filaments. I tested six of these motors on a skid-steer rover driven by a single l293d and a beefy 3s lipo battery and they all handled 12v without issue. These motors are pretty quick running this much voltage but the plastic gears are not expected to hold up for long so have fun.

Great for my small STEM projects. Convenient connectors for solderless breadboards, but wire is long enough if you need to strip it to solder or attach to a motor shield, just be careful with the little tabs where the cable is soldered to, they are very thin and fragile so don't bend them.

They work and delivered on time.

These motors are supposed to be average...but they are not. The actuall motor that drives the gear system inside is perfectly fine. However the gear system itself is compermised: If the wheel is given enough force to push, you will hear a clicking sound and the motor will keep moving, but the wheel will remain still. This is a sign of a malfunctioning gear system. And, no, i'm not pushing the motor too hard past its limits - other brands who make the same gear system have taken full advantage of the motor. I highly reccomend the MOTOR itself...just not from this seller.

The first set I bought came with one defective motor. I exchanged. In the 2nd one, 2 motors stopped working in a month. Will not recommend this product.
