I chose it over other brands because of the ""amazonbasics"" label. Thought I could trust Amazon. The mat works fine, but it has extremely strong chemical odor, even after weeks of use. When I transported it in my car from home to office, the odor filled my car during the trip, that I had to leave my car windows open the entire day to get rid of it. Such strong chemical odor made me fear that it is made of harmful materials.
