AquaSonic Elite Rechargeable Electric Toothbrush Set - ADA Accepted, 5 Modes, Travel Case, 8 Brush Heads (Optic White)

I bought the Elite Ultra Whitening because it provides 8 Proflex brush heads with a better motor speed (50,000 VPM). The Proflex brush head is a little firmer than the Aquasonic regular one. I am very happy with the soft/firm bristles. Some Philips Sonicare models are expensive and the replacement tooth heads cost about $7 to $8. The Aquasonic supplies 8 brush heads and the Sonicare only supplies one. Over the years, I observed the Sonicare electric toothbrush lasts 2 to 3 years. Each charge of Aquasonic can last 30 days and the Sonicare charge only last 14 days The vibration of Aquasonic is not as strong as the Philips Sonicare 4100 Series and the handle of the toothbrush is not shaky. As a senior (over 75 years old), I do not want a strong vibration for my aged teeth. Their customer support center is friendly and answer the enquiry quickly in one or two days but they do not provide a phone number. Drawback: It is very easy and sensitive to touch the power button which would shut down the motor immediately. There is no explanation of different modes in the user instruction booklet. Overall, there is not much significant differences between Aquasonic and the other brand name in cleaning. Aquasonic offers a lot of functions including Deep Clean with a reasonable price
