Oral-BiO Series Ultimate Clean Electric Toothbrush Replacement Brush Heads for an Oral-B Electric Toothbrush, 4 count, Black

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.

Received this order quickly. Desperately needed replacement heads. Once I got the new part installed, the brushing experience was so much better. It also helped that I read instructions about daily cleaning. It has made a difference. Would recommend this package as the one in warehouse is 8 pieces

This was a perfect match to my new toothbrush that needed a refill. These brush heads get the job done and last longer than others. They work great on the gum setting of the toothbrush and are soft.

They worked well and seem like good brushed for the oral B

Muy buen producto para el cepillado de los dientes. Es fácil de usar y suave con la dentadura. El estuche en el que viene facilita su transporte cuando a uno le toca viajar y el tiempo necesario para recargar la batería es corto. Hasta ahora solo puedo reportar buenas impresiones. Espero el producto dure mucho tiempo.

Best bang for your buck. Cheapest deal I have found on the IO tooth brush heads. True to description.

These Oral-B replacement heads are fantastic! I’ll absolutely buy them again.
