Right. Nothing is perfect. But in sustained heavy rain, I'm going to get soaked, whether I wear something breathable, non-breathable, or nothing at all. The question is not how to stay dry, it's how to stay comfortable while wet.

It's a really strange jacket. It's not very warm. What do I mean by that? If I layer up with the jacket on top and then go out in really cold weather, I don't feel warm. I feel cool. I'm warm enough not to panic and worry but not as warm as a traditional coat. This is a tradeoff worth making, because I can cycle vigorously without overheating. It is comfortable in a wide range of temperatures.
