[This review was collected as part of a promotion.] For some reason my unit when first turns on is on half power, vibration of brush is minimal. I need to turn brush on and off several times to get vibration intensity to where it needs to be.
[This review was collected as part of a promotion.] I purchased to replace a sonic that I have had for years and seemed to be slowing up. This one is much more lively and refreshing.
[This review was collected as part of a promotion.] The brush is compact yet powerful. I like the two speed option and timer. Brush cleans thoroughly and efficiently.
I bought a new one as it was time and was very disappointed that you did not include a new wall plug, instead it's USB to charge. I don't keep a USB block in my bathroom, why would you do this???
No, I would not recommend this to a friend.

Hi there,
Thank you for writing your review. We are sorry to hear that you are not satisfied with our decision to not provide a charger with your Philips Sonicare 4100 Series Toothbrush.
At Philips, we are committed to reducing plastic waste. As part of our environmental efforts, some Philips products no longer come with a USB power adapter. While this may seem inconvenient, we assure you that it is because most consumers already own one or more USB wall adapters. We will continue supplying USB charging cables with the product that can be used with a USB power adapter.
If you already own a USB power adapter, please ensure that it is certified and meets safety standards, ideally from a trustworthy brand. The safety standards for safe charging are as follows: Input voltage: 100-240V; Output voltage: 5V; Power output: 1A or higher. If you want to use or charge your product in a moist environment, such as in the bathroom, always use a splash-proof (IPX4) rated adapter.
If this does not help or if you need any further assistance, we kindly ask you to reach out to us via social media. We are available on Facebook (@Philips) and X (@PhilipsCare). Don’t worry if you don’t use social media; you can also contact us through our contact page: www.Philips.com/contact.
