iO Ultimate Clean Electric Toothbrush Head, Oral B Electric Toothbrush Heads, Twisted & Angled Bristles for Deeper Plaque Removal, Pack of 4 Toothbrush Heads, Suitable for Mailbox, White

They were very good.

Amazing teeth have never felt so thoroughly cleaned.

Generally I find the Oral-B IO toothbrush design to be far superior to the Oral-B Pro range that it replaces and teeth feel significantly cleaner after use. These replacement heads are expensive but unlike the 3rd party varieties I've tried which are far noisier and rattle themselves apart in a few weeks, these are quiet and last long enough to need replacing due to the brush filament wearing out. I've dropped it by one star due to the utterly insane identifying scheme that allows multiple family members to identify which brush head is theirs. On the Oral-B Pro, an interchangeable colour ring was available on each brush head, which worked exceptionally well on early blurry mornings to identify who's whose. These IO heads have a permanent tiny symbol printed on them in a colour carefully selected to be as close to that of the plastic itself as possible. When I get up I can barely focus on the brush head, let alone the ghost-like microscopic symbol, and so this makes for a surprisingly annoying feature of the design that is frustrating and unexpected especially given the cost. In comparison the 3rd party products I've tried have a huge 5mm wide bright colour band on them for less than a quarter of the money.

I bought these Oral-B iO Ultimate Clean replacement heads to keep my iO toothbrush performing as it should. They fit perfectly and are easy to swap over. In use, they clean very effectively and feel noticeably thorough, especially around the gum line and between teeth. The twisted and angled bristles do a good job without feeling harsh. Build quality feels high, and they hold their shape well rather than splaying out quickly. Like all iO heads, they’re not cheap, but performance is consistently good. Overall, a solid replacement option that maintains the cleaning quality you expect from the iO system.

Good

Proper quality heads. I figured might as well get the original ones rather than copies to save a few quid.

Best value you will find these for. Legit product
