[This review was collected as part of a promotion.] Best toothbrush I've ever had. Do not like the new USB charger, but I still have my old charge stand. I got the A3 brushes and the clean is phenomenal! Highly recommend.
[This review was collected as part of a promotion.] love it cleans much better than my toothbrush. Teeth never this clean over the last 50 years. Best Christmas ever
[This review was collected as part of a promotion.] The bristles are very hard and it seems to brush aggressively. I have been used to a soft bristle brush. Sometimes it does not aggitate at all but just hums so I have to turn it off and on again.
[This review was collected as part of a promotion.] 4100 series electric toothbrush. This is an excellent product, especially for a person with gum disease. My teeth are perfectly clean without applying any kind of pressure. I highly recommend this toothbrush.
[This review was collected as part of a promotion.] Very nice product. Much improved from old design. However, pressure sensor is not well described, particularly whether/how it resets.
