I bought the pylons to make on a farm, the basic exercises with the motorcycle. For the cones were suitable. But in general, the processing is not so great. The white stripes are not painted but only stuck. The weight is also very low, so the pylons already flying in a small gust of wind away (had 2 successive set).
I would say it depends on the reason for the use of. Unattended I would leave this out not because it does not guarantee to stop.
