It is good and the feeling is dentist clean after usage. But few times I’ve noticed that it left spots behind. Clearly visible on my teeth like after I ate berries or something with rich color. I switch to handheld for those sometimes. Overall, it is pretty good clean and I’m happy with it.
This product is made with a great material, it is very adequate and it carries the ultrasonic vibration very similar to the more expensive Philips sonicare toothbrush heads. The only con I would have against this product is I feel that the blue indicator bristles wear down to fast, or maybe my teeth are just that dirty. I don't know but I will purchase again.
