Update: It's been about 3 weeks and the tip is still great. As you can see in the photo, the bristles are still firmly attached to each other and do not crumble. Still very satisfied and would definitely buy again. I have had an Oral-B electric toothbrush for about a year and a half now. I have used the original nozzles that came with the toothbrush for some time. When it came time to replace them, I settled on generic replacements (thought they were close enough). I didn't realize how wrong I was until I cleaned this Oral-B replacement brush head. Pros: 1) The bristles on this Oral-B brush head feel and look much better than the regular bristles. 2) I would set the brush hardness to soft to medium. 3) Genuine packaging from Oral-B (it was German but everything was Oral-B). 4) The price is the best I've found for real Oral-B tips. (I've searched everywhere and couldn't find them anywhere cheaper.) Overall, I'm very happy with my purchase and would highly recommend the tips.
