They don't last as long as Oral-B's so even though you get a lot, you have to replace the head a lot.

Some of them doesn’t fit well that they come off from the body while brushing.

don't buy these. absolute junk. have had them for one week and three brushes heads already quit turning. not worth the money. buy the original.

The heads are loose on the toothbrush. Will not purchase again.

Breaks easily.

Too soft, ended up ordering OEM. These work, but are terrible don't feel like they clean at all.

Good price but bummed they don’t brush the same as the toothbrush heads that came with my oral b. They feel different and the vibration is irritating. Trying to suck it up but overall probably will splurge for the real ones next time.

I'm always thinking my gums or tounge are going to get pinched, there's a space there that every once in awhile gets a little tug, believe me I have my finger on the shut off just in case, VERY SCARY!

Did not fit the description as a replacement as its bristles were way to light unless you have ultra sensitive teeth and gums. Also the opening on the side kept snagging the inside of my cheeks causing blisters and bruising in the mouth.

The brushes don't fit tight enough on a Braun toothbrush. While brushing, the product has a tendency to come off in one's mouth. Otherwise, great for the quantity and price.
