I took my SES checkride with Heidi Ruess this past Sunday and earned my SES rating. I must say that all other comments about her are spot on, she comes across as soft and a bit mild-mannered, but she can definitely still fly an airplane!
She is very thorough, and doesn't try to trick you. If she does ask a question that you don't thoroughly answer, it seems that she'll talk you through it and give a great personal story as an example. I learned an incredible amount from her in the 4 hours we tested.
