A secured transaction is a transaction that is founded on a security agreement. A security agreement is a provision in a business transaction in which the obligor, or debtor, in the agreement gives to the creditor the right to own property owned or held by the debtor.
If your brush has two speeds, and uses brush heads with slim-angled necks, then you have a Sonicare Elite. An Elite toothbrush has a thread collar screw on brush head.
The Oral-B Pulsonic is a wonderful addition to the rechargeable electric/sonic toothbrush market. It is more slender, more quiet than the Philips Sonicare Flexcare Rechargeable Sonic Toothbrush I own, although it doesn't have as many features. Both clean equally well; you'll notice whiter teeth within a few days of use.
