Changed my life.
LITERALLY CHANGED MY LIFE. I’m not afraid to admit I never got over hating brushing my teeth since I was a kid, and this has completely and utterly changed me - and I’m not even being dramatic! Their coverage feature has gamified the experience of brushing my teeth, since I want a perfect score every time. It’s easy to use (the end lights up yellow and blue depending on coverage), and has so many different modes - I also enjoy seeing the timer properly and knowing how long I’ve brushed for. Also, the new cap is genius - no bathroom particles actually access the brush now. Super easy to charge too, with a cup or in an on the go pod. The best brush I’ve ever had 10000%.

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.
