[This review was collected as part of a promotion.] I only recieved the tooth brush heads and no tooth brush to go with it so I couldn't test it out. I'm not able to test a proudct if I don't have all of the product to do so. I only got two of the tooth brush heads in the mail. It looks like it would have been an amazing product to test out.

They do a terrible job of letting you know which heads will be compatible with your current toothbrush online. When going to choose replacements heads there are only two options; one being electric heads implying that all the electric heads will fit all electric toothbrushes. Not the case!

I have the IO toothbrush and it’s great but…..This is a review for the gentle brush head but it is not gentle at all. Brush bristles are too stiff and hard on the gums. Without a softer brush head I won’t use it. They need to make a softer brush head something like Tepe or Nimbus manual toothbrush they are extra soft.

I have an oral-B toothbrush, but this was the wrong item
