I ordered these off of Amazon and threw them in the closet. By the time I needed them, I got them out and realized that they were not the correct replacement for the toothbrush that I have. There are three unopened heads and one that I did open looked at (and realized it was not going to fit my brush) and put it back in the package. It was not used. My return date to Amazon has passed. Just want to get these to someone who can use them rather than toss them out.
