Review on 16PCS KHBD Replacement Toothbrush Heads - Compatible with Oral B Braun Electric Toothbrush Handles: Oral b Pro 1000 7000 1500, Smart Genius 8000 Vitality by Nicole Fisher

Good fit. I've only tried one, but there are 15 more to come. Still, this first one was disappointing, but I hope others aren't disappointed. During my first cleanse, I felt something strange before I finished the two minute cleanse. It was stubble (never experienced years of use by Braun). But I thought I got what I paid for. Then, a few days ago, something stranger was in my mouth. Since this item was much more visible, I found a pin after spitting. Apparently from the hole in the back it seems to help the brush head rotate. At the same time, the head now only vibrates and does not rotate. Needs to be updated in the future for the performance of other brushes.
