The Structure of Scientific Revolutions: 50th Anniversary EditionA good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were and still are. The Structure of Scientific Revolutions is that kind of book. When it was first published in 1962, it was a landmark event in the history and philosophy of science. Fifty

They work great!
My son loves his vibrating toothbrush and it needed a new head. We change the head out every time he is sick and he was just getting over Covid. The brush head is high quality, it doesn’t shed and fits perfectly. The cost per brush is excellent! We will definitely be purchasing again.

Perfect fit
Perfect fit for the toothbrush. We have a different brand of toothbrush (also from Amazon) but it has been discontinued. But these replacements fit perfectly.
