great tool in helping to maintain a healthy mouth [SEP] so much better results than a manual toothbrush so much better than a battery operated toothbrush this really does a good job getting the teeth and gum area clean definitely helps in keeping mouth healthy i have a used a few brands and they all do a good job some last longer than others some have replacement heads that can be purchased as generic some dont i usually purchased the name brand replacements anyway i was always happy with my toothbrush
