Quality great
I compare the new brush side to side with the one I had bought about 3 years ago.  The quality of the brush has decreased.  The new brush (size 150mm) comes with sharp plastic like brush head, instead of the smooth silicon brush head I have had on the old brush.  The new one even has a little crack where the brush head and handle meets. Whereas, the old one is seamless.  Very disappointed with this purchase.
