Absolutely love this! I never thought I’d ever be so excited about a toothbrush but this is next level! So powerful and the charge is fantastic. I was expecting a little bit of sensitivity while using the whitening strips but they were a dream! No sensitivity at all and I really noticed a different in the shade of my teeth! Will definitely repurchase to top up! Also have to mention the packaging is beautiful and so nicely put together, it really is a lovely finishing touch! Really pleased with the purchase and will definitely buy another for potential Christmas gifts!
