Review (1/5): Very smelly brushes
As other reviewers note, these things smell atrocious. I thought perhaps they would stop stinking so bad after sitting around in open air for a while, but as yet they have not. The smell clings to things stored in proximity to the brushes as well, and also lingers on one's hands after using the brushes. However, if you enjoy the smell of a nice bicycle tyre on a hot day, you may find the user experience satisfying.
