The brush of brown are great made and very durable. As explained to me the rotating brush head is secured, for example by a thread. This is to prevent that you accidentally swallowed when the unlikely event that it triggers him from the brush neck. The brushes engage very closely on a creel and can be easily cleaned. The progress of wear can be recognized by the blue indicator bristles that with increasing wear lose the color. The brush heads fit universally on most electric toothbrushes from Braun, also on the older models.
Since the brush of brown but not exactly discount products, it is useful to gain a price advantage with large packs. Because the brushes have no expiration date and even if you have to buy yourself a new device, they can be used with virtually all Braun toothbrushes further because of their compatibility.
