These replacement heads are nice and gentle but give that superior clean feeling

I didn't believe that iO series can make any difference but believe me - it does.Sadly heads are more expensive than the old versions but this kind of difference that I noticed on my teeth it's worth to pay extra.

It's the original replacements. Pricey but you have to get the original..

Good tooth brush easy to get new brushes.

good quality good price to value for the money soft on your gums

The gentle brushes are perfect to keep my husbands teeth clean gently following facial surgery.

super fast delivery, sensible packaging that fits through your letter box. genuine brush heads at good price, what's not to like 👌

Ultimate clean murdered my gums. Gentle care brought them back from the dead.£27 for resurrection of my gums was worth it.However I would mention that it's still more than I'd like to pay.After using ultimate clean for a while I still saw no blood but my gums hurt so much I could barely look at my toothbrush. I didnt like the sound of gentle care because I want clean white teeth, not gently cared for teeth so I stuck for the one that has clean in the name - up until pain forced me into using gentle care.Turns out gentle care is actually pretty good. My gums were resurrected after a few days and if I do it right they feel squeaky clean.My girlfriend however used my gentle care brush head twice and now the bristles are bent at unseemly angles. She loves to abuse her teeth so it's understandable - apparently the big red warning light that shes pressing too hard and the suffocated sound coming from the toothbrush isn't enough for her to realise that she should lighten up a bit."the suffocation noises from the toothbrush simply mean success"From now on she uses my ultimate clean head.Above are photos of before and after she used the head.Evidently durability in extreme situations could be improved.I like the heads tho they spin left and right really smoothly if u move them with your finger it's cool.Please fix the durability though - for just under £7 a head I think I deserve at least that. Thanks :).And with ultimate clean if you could remove the raised bits around the sides of the head and make it more similar to cross-action, I think theyd be much more gum-friendly.Cross action was amazing I loved it it felt like a pneumatic drill at the same time as not damaging my teeth, but I prefer the quieter io motor for night-time, since I like to go to bed late when everyone's asleep.
