[This review was collected as part of a promotion.] I had another Philips Sonic electric toothbrush for about 10 years and it was great. Unfortunately I didn’t look at the model number of that one before I discarded it and it was much better than the 4100, I thought they looked exactly the same. . I now have to purchase another one because the 4100 just isn’t powerful enough and my teeth don’t even feel clean like they did before. If it’s your first, you might like it but I did mess up and obviously downgraded quite a bit.
[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.] 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.
