I've been buying these replacement tips for over a year now and have had no problems with them. These nozzles are good and last a long time. I don't know if they're real or not, but I know they work and work well. The photos below show the brush head after two months of use and it is still working perfectly. I would recommend them for the price rather than risk buying the cheaper ones with mixed reviews. Spend a little more for the quality you need when it comes to teeth.
