Review on Enhance Your Oral Care Routine with Oral-B Dual Clean Replacement Electric Toothbrush Brush Heads - 3ct by Catherine Buhr

I have just received 3 packs. I agree with the 2 star rating and ALL of Kenda's comments. "I would also add that the metal mechanism inside the brush head makes a loud 'click' noise and the brush head slides up the pin. I had to stop and press again every 15 seconds. I removed the brush head hoping it would fit better when I put it back on and it took a bit of rotating the brushes to get it to fit again. Apparently the brushes included in these US/Canadian 3 piece sets have a design flaw. I've been using Oral-B Dual Clean replacement tips for years and they are Made in Germany and not identical to the previous version.
