Genuine Original Oral-B Braun Precision Clean Replacement Rechargeable Toothbrush Heads (10 Count) - International Version, German Packaging

They seem to be pretty good.

I was a little worried they may not fit perfectly but they do and are a good product. And much less expensive than buying at retail chain.

3times the number of heads for the price vs store bought and original Oral B heads not generic

Chinese knock-offs will rip up your gums.

I cant really tell anything about longevity or durability.

Ive been using this product for quite awhile and liked it, but wanting to save some $ tried an off-brand through my pharmacy/insurance network. Well, Im back to this one - by far the best in terms of longevity, durability and value. Dont be concerned that the description says German, as it doesnt affect the quality or use.

Works perfect, fits my oral-b electric brush

These are great refills for my toothbrush and I like I can get them on Amazon, quickly and in bulk!

Product worked well. Exactly what I ordered

Love my toothbrush - replacement heads are good value
