Excellent value for generic head replacements.
Worked perfectly with my kids sonicare.  My dtr has been using it twice a day for the past month and no issues with bristle fall outs or heads detaching from the base. The bristles are just as soft as the originals were, which is what is recommended by dentists. I am REALLY happy I don't have to pay for the brand name replacement heads or compromise on quality.
