According to my experience, these reflective distancing cones serve their purpose of keeping individuals safe and aware of their surroundings. They are easy to spot, even in dimly lit conditions. The reflective material reflects bright even in the darkest places. It's an eco-friendly and sturdy product. The con is that the reflective material gets dull after a few months of use, but this can be easily solved by replacing it with new reflective tape. This product is a must-have for any workplace that values safety.
