I already had a triangle that came as standard with my car but because I planned to motor to Spain I decided to get a second one in order to avoid any roadside hassle from the Spanish authorities - apparently you are required to place them about 30 metres behind AND in front of the vehicle. I was pleasantly surprised by the quality of this item - it is robust and well constructed, and heavier than I expected, and WILL stand up to a strong wind. It folds up neatly into its storage case. I can't see how this can be sold for £3 including delivery, and still make a profit. Buy it.
