Bayer Electric Toothbrush Head Original Universal Brush Replacement Head Bruch Head 4 Pack Fit X1/X5/X9/X12 Non-Bayer

Since I got the Bayer electric toothbrush X1s Plus during the 2018 Double Eleven, this is already the 6th year. I can't count how many times I've dropped it, but the quality is still rock solid. It's super durable. I haven't had a chance to switch to a new toothbrush, so I just buy a new set of brush heads every year. I do want to mention that the brush heads seem to be getting pricier. At first, they were quite affordable, and there used to be mini brush heads that made it easy to reach the back teeth, which was really convenient. I hope the brand takes feedback from loyal users like me into account.
