Today I found out there is actually a difference between hair brushes. What amazing discovery did you recently make?

Yesterday I bought a new hair brush because my old one was broken.
Today I used it for the first time and, amazingly, found out that with this brush I can brush my hair much easier, without losing hands full of them.
Had I known this before I probably would have had more hairs left.
So, what discovery you did recently?
One that you could simply not believe that you didn’t knew it before?
