I only use them to walk the 7 blocks to work or while waiting for the bus. I double them because it makes them feel more secure. I got four for the price of one of the others I've seen. I kept two for myself and sent two to my daughter. I do not regret the purchase. You just have to understand that they are very light and thin. They're also a little big, so it's not that easy to move your head. But they serve the purpose I bought them for.
