"Super bright light, Cord not long enough."
Great product! Super bright light! I install weekend signs for home builders and it's perfect for getting people to pay attention to the fact that I'm on the side of the road. The disclaimer for the product says the magnet that holds the unit on may dislodge after 40mph, it doesn't. At 75 miles an hour it doesn't budge. The only drawback is that it comes with an 11 foot cord which is not quite long enough for me. In my opinion they need to extend the cord to about 16 feet. Overall, great product, very durable! I bought two of them and so far, they work very well.
