Oral-BiO Series Ultimate Clean Electric Toothbrush Replacement Brush Heads for an Oral-B Electric Toothbrush, 2 count, White

I absolutely love these Oral-B toothbrush heads! Every time I switch out the old one for a new head, it feels like I’m using a brand new toothbrush. The bristles are perfectly firm—not too hard, but just the right amount of pressure to give my teeth a thorough, refreshing clean.What I really appreciate is how they maintain that fresh, just-out-of-the-box feeling with each replacement. They snap on easily and fit securely, just like the original. The difference in how clean my teeth feel after changing the head is noticeable—it really does make me look forward to brushing!If you want to keep your electric toothbrush feeling new without constantly buying a whole new unit, these replacement heads are a must. They’re high-quality and make maintaining good oral hygiene a breeze!

This review is for (1) 2-Pack Oral B Ultimate Clean heads from A 2 Z STORE at $20:Packaging and brush heads appear genuine Oral-B in all regards. Packaging seems new and fresh, no signs of aging or abuse. And the price is less than retail.I ordered generic replacement heads on my Amazon Vine product testing account but did not even try them. They do not match the iO Oral-B proprietary fitting which is universal to all iO toothbrushes. iO uses a linear magnetic drive that employs a piston in the handle that is driven by a motor to move in a linear direction up and down. The iO head converts that motion into an oscillating motion at the bristles. The connection between the head and the piston in the handle is by a magnet atop the piston and a plate in the head. It is a smooth, even and gentle contact that somehow also produces "micro-vibrations".The generic replacement heads have a spring-loaded plunger that takes the linear motion of the piston and converts it to oscillating motion at the bristles. The connection is therefore a single point of impact against the strength of the spring which, IMO, could compromise the motor and drive mechanism in the handle.iO toothbrushes cost from $60 to $360. Is it worth the risk to use a cheaper, truly non-compatible replacement head when the cost of genuine Oral-B iO heads is about $.15 per brushing (based on 60 brushings at $10 per head)? You be the judge.

These are great!! I recently upgraded to these style brushes and my dentist really noticed a difference. The design is a sleek and it's cleaning ability is fantastic. I always keep mine on the charger and it's never a problem.

Cheaper than in-store and product works great, do wish the brushes were a bit bigger though.

Good quality, like the head that came with brush.. I tried others, not the same.Love color changes in the head to let me know when to change brush

No need to worry about the fit or quality. You can’t go wrong with the original product.5 stars ⭐️ ⭐️⭐️⭐️⭐️

Always have no problem with these refills. They are perfect.
