It's interesting you like Frogs but have trouble with Eggbeaters. The engage system is similar. With some pedals (like my Time Z Control) you "click" and slid. With Frogs and Beaters you just slid so what you do is just start pedaling and the cleat engages. If you try stomping on them hoping the cleat will "click" it won't work. Beaters are really easy to get into. Maybe your cleat was not properly adjusted (is it facing the right way?).
