It's the only device of it's type i've purchased. I am buying one right now with my own money to cover me until my department's slow purchasing process successfully procures another set of these cones.

The lights work great (two settings) arriving at dusk, the lights really help. The led illuminates well, but note that the ledilluminates internally. One minor con is that the light circuitry is in the base.

Opening the cone up is a breeze. Collapsing is a little trickier. Better - it collapses down into it's base for easy storage. The surface is reflective enough to catch car headlights.

I use these as a firefighter. Bought this to carry on my garden tractor to put out when im plowing driveways. I read reviews and purchased this cone after reading a fire dept employee purchased these and said they are quality.

This cone is sturdy and large but the light does not work. The base is not strong and it will no longer stand on it's own. Just use it as a cone now.
