Good quality

Great value and the function as expected.

Since there is no photo to show these in scale like next to a hand or a dollar bill or something and the sizes of M whatever are a mystery to me, I ordered these hoping one would be the right size for my table saw's arbor. They're all way too small, the largest being maybe the size of a nickel. It would be helpful to future buyers to know exactly what an M1 M2 etc. sizes were in English/Imperial measurements.

The overall sizes on these are fine but they are not flexible. Usually a spring washer has some give and flexibility. You can even fold it in half. These are very rigid. I tried these in a plumbing application and because they aren't spring like it was a failure.

Good product Well packaged

The largest size is M14, not M16. Product is mislabeled. I measured them all with calipers, all except the "M16" ones are labeled correctly. Unfortunately, M16 is the only size i actually needed today.

These wavy washers were recommended as a potential fix for a stroller wheel that was wobbling when being pushed. What I really needed was a flexible washer that could be snapped into place with the wheel. Plus, the largest size in this box was not big enough.
