After using a campbell lather machine I thought I would give my opinion.
The lather isn't as thick as I usually get with my brush and Bigelow shave cream. But I sure do like the lather being so hot. It also is easy to re lather for additional passes, just press the button and you have another handful of lather. I used Campbell lather concentrate which has a pleasant smell. I have decided to use the lather machine during the winter and as the weather warms up I will switch back to my badger brush and Bigelow shave cream.
