Count us as fans of Dinotte. We use a Dinotte 140R on every ride and I've just purchased a 300R to replace it. There's no way that a $25 blinky is going to compare with a Dinotte taillight, even if it is a Turbo Superflash. The dazzling flash pattern of the Superflash impresses people in the bike store, but it just doesn't cut it on the road, especially in bright daylight. It's not only the brightness of the Dinotte that makes it superior, it's the fact that it's a true, deep red. Oh, and their customer service is second to none.
