Thanks again guys. One thing I didn't mention in the video, is based off my test lather with MW, and the feel of the brush then, I was ready going into this video to give the knot a negative review. I really did not like the feel of it. I was almost like some of the older generations of synthetics in feel (kind of sticky, and too springy). But one I got actual lather into it, the feel totally changed. My brain did a 180 mid-video.
Still not sure why it had a hard time with MW. It's my favorite soap, and this is the first time I've ever had an issue lathering it. I'll have to do some additional testing.
