Works great

I've bought cheap replacements that did not hold up. These seem just fine in that regard, and in terms of cleaning my teeth, I can't tell the difference. However, they don't attach as securely to the brush handle as securely (though I haven't had one fall off in use).

Great for the money. But they're stiff and with continued use you'll get a receding gum like which will end up costing an arm and leg. If not irreparable damage which is worse with a lot of pain.

Buena inversión

You get a lot of value for the amount paid compared to the genuine/original Oral-B brand brush head. I would say that the bristles do wear out a little faster than the original/genuine ones. I had to change the first one used a little over a month. It should last at least 2 months before wearing out like it did with me.

They worked well with my tooth brush, they don't last as long as the original, but on a per piece basis they are an excellent value. Even though I replace more often, the cost is lower. They appear to work just as well as the original one.

Kinda loose but doesn't effect how it works. Which I was shocked. But it works like they should.

Does the job. I replace my toothbrush once a month this is a great solution.

Overall good product. Had to throw some away because they didnt quite fit right. Basically too loose where they don't fully engaged the toothbrush and don't fully vibrate. Because of the low cost per brush I still feel like it's a good deal and would buy again.

About 70% off of the cost of replacements at COSTCO and on sale too. Fit properly and work like the ones that came with the toothbrush when new. Great value.
