Query: Best swaddler we've tried

We started out using the Swaddleme swaddlers, but when our baby got to be about 6 weeks old she learned to wriggle out of them. This kind, with the zipper, keeps her in! As soon as we put her in her swaddler, she seems to know that it is time to go to sleep. It soothes her and keeps her warm. We have a cotton one for the summer and a micro-fleece for the winter. The only downside is that they're pretty pricey... oh well.
