The cones are very stable and robust.
In my training there was every now and then also times that I stepped on a hat with cleats.
Here, I could not detect any signs of fatigue (cracks, breaks, etc.).
With a total number of 50 cones, it would be for me but also very good manageable if even a little hat would go broke,
Since I mostly train on grass (artificial turf rarely), I realized that in wet soil the hat are dirty.
That is, the wet grass, possibly stick a little earth even to the hat.
Since the cones are made of plastic, I simply put then into the shower.
The additional support is simple, but practical.
For me, the cones are always in the trunk, so I have them always ready for a training session.
I am very satisfied (see review) and would buy it again.
For further inquiries, I am happy to help.
