I already know the latest toothbrush output in September to have it tested. This brush Pro 700 FlossAction I think is much lower because it is a little too brutal for the gums. My dentist's strongly discourages. What I dislike the most part is that there is only one possible method of brushing, and it is a little too bright. The brush itself is fine, I have no complaints. I will use it against the other by model I own (with four brushing modes, including a soft, recommended not to attack the gums).
