I use them and actually like them a lot. I was suspicious of the oils when my wife decided it would make a good insertion into my 25 year routine. They are thick (maybe not all but mine is). I did not like how it slicked my hand prior to using the razor but I've adjusted the application process to eliminate the issue as we'll. after a couple weeks I noticed the shave is smoother. It's a slight and perhaps barely noticeable nuance but the oil in combination with the lather makes my skin glide against the blade better. It's "polish" per se and not necessary but I like the shave and my skin when it's done.
