"I love the innovative colour changing brush head as I'm guilty of not changing brush heads as often as one should so this is a handy little reminder"
"Very helpful to have the indicators on these heads so you know when to change to heads based on your actual use and not an arbitrary time period"
"These are amazing teeth feel so clean Having the reminder to change the heads when ready is an excellent idea"
"Love the extra feature of the bristles fading from bright green to yellow which reminds me when it's time to change my brush head"
