Review (1/5): don't buy the bonus pack - the brush is a piece of crap.
I went to the Navy Exchange to buy a new shaving cream brush. They were not selling the individual brushes, but had this brush included in this "bump patrol bonus pack". I thought to myself, "I do have a very sensitive face that gets bumps when I shave, I'll go ahead and give this a shot!". I bought the whole pack mainly for the brush. The brush had several problems. First, the bristles are very rough - they do not flex while shaving, and they do not soften with warm water. Second, the bristles fall out on the first shave - getting caught up in the razor and complicating my shave. Third, the bristles are shaped such that you only get about 1/3rd of the bristles of surface contact, unless you REALLY mash this thing into your face (keep in mind, brittle bristles makes this very uncomfortable). By the end of the ordeal even using the bump patrol cream, I think my face is more irritated than it would have been had I never touched the brush in the first place.
If you need to use the treatment, don't buy the bonus pack - the brush is a piece of crap.
