The E3 from CASO Design is very similar to the exterior style of the E9: the materials used here are particularly impressive. We couldn't find much fault with the quality of the eggs, even if the cooking process seemed a little lengthy in parts; only medium-grade eggs, which are supposed to be waxy soft, can get a dry-looking egg white in this model...

An infinitely variable control dial for the desired degree of hardness of the eggs from soft to hard (cooking time up to 15 min) is the special feature of the Caso model in the test field. The eggs cook as desired. Operation and cleaning are uncomplicated.
