I've been using the NACARUM Caution Pennant Banner Flag for a few months now, and it's been a game-changer for marking hazardous areas on my property. The bright yellow color and bold 'CAUTION' lettering are impossible to miss, even from a distance.

What really stands out is the durability. We've had some serious windstorms, and the double-stitched flags are still securely attached to the rope. The PVC mesh material hasn't frayed or torn, which is impressive considering the abuse it's taken from the elements.

I initially bought these to mark a steep drop-off near our driveway after some close calls with delivery drivers. The 36-foot length was perfect for running along the danger zone, and the flapping motion of the flags naturally draws attention to the hazard.

One thing to note - like another reviewer mentioned, the printing is only on one side. This hasn't been an issue for me, but it's worth considering if you need visibility from all angles. Also, while they're great for daylight visibility, they don't reflect at night.

Compared to standard caution tape, these flags are in a different league. They look more professional, last longer, and actually command attention rather than blending into the background. For the price, they're an excellent value that could literally prevent accidents.
