I recently acquired an M6 in Manchurian. Upon initial receipt I was extremely disappointed. I have since used it 5-6 times and I am delighted to say I truly enjoy this brush now. I still feel the knot appears to be undersized or the hair weight was off during production. Traditionally bowl lather but for some reason, the second use I face lathered with it. The handle is very comfortable and it whips up a great lather. The knot just works for face lathering. Can't say I will only face lather from this point but with that brush I will.
