A worldwide leader in consumer electronic products, Philips also offers high quality oral care products for the entire family. The Sonicare is a rechargeable electric toothbrush that is designed for kids. Since it operates on a rechargeable battery, there is no need to buy standard AA or AAA batteries. The packages of the Sonicare may include coupons on other Philips oral care products including tooth brushes, brush heads, chargers, and more. Additionally, these oral products may also have coupons on other Philips healthcare products such as shavers for men. Besides coupons, the packages may include small brochures about future products such as new versions of electric toothbrushes.
The Philips Sonicare toothbrush, with soft bristle tips that vibrate at ultra-high speeds, has been clinically proven to clean 20% more plaque from the surface of your teeth than that of a manual toothbrush. Additionally, it also eliminates the guesswork involved with determining how long to brush, with its built-in timers, and the amount of pressure needed to adequately clean your teeth. This ultimately results in healthier gums and aids in the prevention of tooth and gum disease.
The most obvious difference between low cost and expensive brushes is going to be durability. Low cost brushes are more likely to fall apart, stain and shed bristles - which can be very annoying when you're trying to remove a single bristle from your canvas for ten minutes. However, with the cons, there are opposing pros to buying inexpensive brushes as well. The most apparent is that if they get messed up, it's not a huge expense to replace them. However, the more expensive a brush is, the more bristles it has so the more consistent your stroke will be.
They will load up with hair and dirt and won't be effective.
