Query: Surprise when I first used the Sonicare 5300 Toothbrush

It was a disappointment when I first used my new Sonicare 5300 toothbrush. It does not have the 30 second reminders like my former toothbrush had. It is usable - and certainly I would not return it after I had used it. I wish Amazon would that information available to all prospective customers.
