Review on 🚦 KAFEEK Reflective Warning Triangle: Ultimate Roadside Safety Kit by Tyrone Lyons

They are designed to be placed on the pavement to protect you and your vehicle when fixing a flat tire or waiting for help. They weigh less than half a pound and have a thin piece of plastic around the inner perimeter and a rickety metal stand. This means they are more likely to be knocked out of position by any vehicle passing at high speed, rendering them useless for their intended purpose. You'll need to keep a stash of bricks in the trunk to keep them in place so you can hope they work as intended. Buy a stamp heavy enough not to be blown off by passing trucks.
