I just got the Revolution and I noticed that there are many tiny bubbles in the shaft's soft outer layer, near the surface. Some of them have the thin bit of silicone covering them ripped open, creating small holes. There are something like 50 such bubbles and holes over the entire shaft.

I also noticed that on the head, there are many small crevices that aren't smooth like the shaft. This seems a little odd as they're concentrated mostly on one area of the head.

Are these normal?
