80Pcs Plastic DIY Robot Gear Kit Gearbox Motor Gear Set for DIY Car Robot

Its amazing with all these gears not a one was the size I needed to fix a small electric motor. The gears look lot bigger in photo. Most of the gears are small 1/2'' or less, few are 1 inch. The shaft sizes were mostly about 1 mm would not fit on the 2 mm shaft. What looks like belts in photo felt more like rubber bands with lots of stretch. No use for me.

This set came with a variety of sizes and styles of gears. One of my daughter's toys had a rotating night light that displayed on the ceiling and the gears gave out so it was stuck. I was able to find replacement gears in this set that did the trick for me and the toy is running great again.

Using these for my HO scale scratch built logging crane. Was planning to have it as a static display. Thinking now of getting a small hobby motor to have it rotate on its base. For the price, can go wrong. Cheaper than scratch built gear wheel.

Not sure of its quality for its specified use but this product is not good for fixing Spirit animated Halloween decorations. A few of the smaller gear are usable but the larger ones are different.

I would have preferred less variety and more quantity of similar sizes and types in case two similar pieces were needed to do the job. I could not use any of the pieces for my project.

I used them in a Harry Potter House Point Display device i made. Worked out very well.

Good variety of gears. Worked well with my sons project. Fast shipment & arrived in perfect condition.

they are gears and do exactly what gears do

Lots of extra gears
