Extra tip useless and original cannot be reattached if removed.
I choose this polisher because the smaller head would let me access the back of my front teeth.  It did do that, however, this is a single use item.  It comes with an extra pointy tip, which I thought would help with between teeth stains.  Well, the diameter of the attaching post is smaller than for the tip which was already attached.  So the pointy tip was useless.  Next, I found out that the original tip could not be reattached.  So, this item is OK to clean your teeth until the original tip becomes loose, then it is useless.  How long that will take, I don’t know, bot one person said it took about one use.  So, I do not recommend this item unless you are looking for a way to throw money away.
