I have the Sonicare Essence 5300 - I love it. Mine, too, beeps every 30 seconds and shuts off automatically after two minutes. It also starts out gentle and works up to standard speed/strength so that your gums can grow accustomed to it. I do notice a difference on my teeth and my gums don't bleed anymore - that is a huge plus. The replacement heads are a little pricey, but when you register it on the website, they send you coupons for $10 off replacement heads. I've noticed that Target and Wal-Mart have dropped their prices on Sonicares recently and they are same price there as at Sam's and Costco (at least in my area).
