The Vengeance Mirror goggles are great for a quick race and also longer distance training. The adjustable strap is perfect and doesn't loosen during the swim, and the eye sockets fit well without letting water in. They also don't mist up much so I've been able to train for up to an hour without having to adjust anything. The only negative I would say is that they do get scratched very easily, so be careful if you have long nails and make sure to store them safely.
