haymikey likes it [SEP] you may have heardsonicare is a fantastic toothbrush system yes well getting a good replacement brush at adecent price is another thing one day i get a good discount on their own name and next time they are outrageouslypriced and i have to get one from the grab bag of brushes offered by someone i have never heard of well i spenta few extra turns of the clock looking as bristles and ratings and decided on jibitee i have had it in use for a week andi am super happy with the option the center bristles are slightly firmer it seems and they really make it more effectiveoverall i cannot tell any feeling of too stiffrealy i have used sonicare for years and jibitee is the best brush replacementso far you will like them i am sure
