Good options to select
I love this toothbrush and I really wasn’t a fan of electric toothbrush’s before this. Always used a manual one. It cleans really well and you can select the different levels of vibrations which is nice. It also tells you when you’ve cleaned certain sections of your teeth and tells you to move on. Overall a great product.

I won't go back to manual now - love how clean it makes my teeth feel
Wow this toothbrush is full of great technology, firstly a timer that tells you if you have brushed for the recommended time and secondly it tells you how much pressure your applying via the base of the brush changes colour. This tooth brush feels premium every accessory you can tell has been especially developed from the stylish black carry case to the chargeable quality glass with gold colour charging base. I thought using a manual brush would clean my teeth just as well.. but no after one use I recongise a complete difference and feel after. There are three setting low, medium and high. My happy place is medium as high was a bit too much and low not enough. I am really enjoying using the brush and my teenager now wants the same one for Christmas. Battery life seems to be a week for me but sometimes I brush three times a day. A really great brush that narrow head allows me to reach to the back of my teeth easily and it's light and easy to hold. Love it!
