Familiarity: I've put it through the wringer
For the price they can't be beat since they come with the ($18) cleats too. Sure, they are a bit heavier than the more expensive versions of Shimano pedals, but they work perfectly. Clip out tension is adjustable over a wide range. Even at the lightest tension they are secure until you want to clip out, then you're out quite easily.
