When I purchased the Arm and Hammer toothbrush, I didn't realize how difficult it would be to locate replacement heads. The store where I bought the brush has NO replacement heads in inventory, so the internet was the next logical place to shop.What made this so difficult is that there was no part number listed on the head itself. I relied on the product description and compatibility chart to choose these heads. When I replaced the head, I noticed that this part didn't fit my brush exactly, so it is on the brush at a slight angle. The brush still works the way it is supposed to, but it is a little awkward to use now.As far as the quality of the brush head, it is fine. It provides a good cleaning and is especially good for the back of the teeth and near the gum line. I'll see how effective it is in a few months when I go for my twice a year cleaning. Read more

2 packages of 2 heads, 4 heads total. Just as expected. They were shrink wrapped together with a note to not separate them, so I assume some of the issues people have mentioned about only receiving 1 pack instead of 2 were warehouse errors rather than a seller error. They do take a bit of force to get them to twist all the way on the handle as I've seen a few reviews mention, but I don't really see that as an issue since it just means it's a tighter fit.

I love these. My local grocers no longer carry the MEDIUM bristle version so I now order them on Amazon! It actually will scrub your teeth and make them clean. Read more

I love the Spinbrush I've been using one for years. I was really happy to find the larger size head. I gave 4 stars only because I thought i was getting 'Medium' grade but I got soft. That's O.k. because it is definitely better than the small ones I had. I did get 4, 2 packs of 2. What would be absolutely wonderful is if I could get some new plastic covers that come with the toothbrush. They tend to get a little cruddy and I don't like my toothbrush to be without a cover. Also it takes some 'muscles' to twist it into place. Don't wimp out twist it! Read more

These are great replacements. If you are doing what you are supposed to by replacing every 3 months These are great to have on hand. They last and are great and stay like new for twice a day brushing for the full 3 months. If you brush 3 times a day still good as the day you started using it and then you don't have to run to the store and buy the whole toothbrush because they don't always have replacement heads.
