Overall, I like the product.I have bought a few of the similars over the years, and generally satisfied with the quality. But One thing that I do not like the most - not environmental friendly because the customers like me can not change the battery ourself and have to throw the entire unit away when the battery is dead, but otherwise the units were still working fine
[This review was collected as part of a promotion.] I have been using for almost a month now. I love the two settings and how long it keeps its charge!
[This review was collected as part of a promotion.] I have used my 4100 series for about a month, brushing twice daily and haven’t had to recharge it yet.
[This review was collected as part of a promotion.] I bought this toothbrush to replace my much more expensive model, which lasted just over a year. I have found that I do not need all the expensive bells and whistles. This toothbrush cleans my teeth as well as if not better than the more expensive model. This is a good tooth brush and I would recommend it.
[This review was collected as part of a promotion.] I've always considered brushing to be an annoying chore, but the 4100 has made me actively look forward to brushing, as it makes me feel like I don't actually have to do a thing and leaves me with the kind of clean mouth feeling that I only get after a visit to the dentist.
[This review was collected as part of a promotion.] I was not looking for ALL the smart features Phillips has to offer but the 4100 was exactly what I was looking for. Compact for travel, quad timer, 2 min Timer etc . I also like the fact it has different intensity’s to choose from! The price is nice as well. I am very happy with this purchase and would purchase it again. I love this toothbrush !
