[This review was collected as part of a promotion.] I didn't think I needed or would like an electric toothbrush, but I was wrong. The Sonic does a great job cleaning my teeth. The brushing action is gentle. The built-in timer is very helpful. My teeth are cleaner than ever.
[This review was collected as part of a promotion.] I've had many previous Sonicare toothbrushes in the past and have been thrilled about them. My last one was the older 4100 model (slightly bigger in size). I received this 4100 as a warranty replacement. Initially I was amazed at how small the body has become. It came with a USB charger instead of AC powered. The annoying part is that you have to provide your own brick.
That is just an annoyance. The real negative part is that now it only lasts FOUR days instead of 2 weeks, like my old model 4100 and what the new 4100 manual says. My usage and charge pattern is IDENTICAL to how I used my old model 4100.
As an Engineer I was fearing this as a smaller size battery usually means a smaller capacity. And it looks like my fear came true.
However, it does the job in cleaning my teeth, as usual.

Hi,
Thanks for your review regarding our Sonicare 4100 Toothbrush. We appreciate your feedback, and can understand that sometimes switching to a different system can take some time to get used to. By switching to a USB charger in our Philips Sonicare 1000-4000 Series alone, we can use up to 189,210 kg less plastic every 4 years. It's great to hear that your new Sonicare is cleaning your teeth as expected, what a shame that the battery is not lasting more than four days. This model should also provide you with 14 days of brushing time, kindly fully charge the battery for 24 hours with no interruptions and try again.
If you have any further questions, please feel free to get in touch via social media. We’re available 24/7 on Facebook and Twitter. Alternatively, you can reach out to us via the contact page on our website www.philips.com/support. One of our colleagues will then try their best to help you further. Hope to speak to you soon!
