This Review Title is Great exchange for plastic I've been using and the content is: Handle is comfortable, bristles are perfectly firm - not too soft/too hard.  After a week of use, not a complaint.  I have used the Bite brushes and find these much better in terms of comfort. Will definitely purchase again.  Edit: Have been using these for over a month now and they are still 5 stars.  All bristles remain intact and are lasting longer than the old plastic ones I've been using my entire life. Strong recommendation for these toothbrushes..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
