They're better than some others I've tried, but none of the cheap replacements are worth buying. They don't last very long and don't clean teeth well. The bristles are not identical to the Sonicare version. As you can see in the photo, these are completely different. Decided to cut my losses, throw these away and buy the real ones from Costco. They last a long time so it won't be too expensive.
