Bests & Worsts Reviews from Amazon

These brush head replacements do not fit correctly on my Professional Precision 1000 Oral B toothbrush. They do not push all the way down, leaving a gap between the bottom of the brush head and the toothbrush's main handle. On my Oral B branded brush head, there is a notch that allows the head to fully slide down, but on these Ogeee brush heads, there is no notch, and they do not fit. Also, while I have not brushed my teeth with these brush heads due to improper fit, the bristles are noticeably softer than my branded Oral B brush heads. It is my personal belief that this softness will result in lower performance, but I cannot test this theory due to the fact that the brush heads do not fit the brush. I submitted 2 images of my toothbrush, one with the Ogeee brand head & one with the Oral B brand head so you can see what I'm describing. You can click on my name above to see the images I submitted. Also, if you scroll down on the home page of this product, you can see customer images located above the reviews that are printed on the right side of the screen.
