Good if you like the smell of strong petroleum! [SEP] Upon opening box we could smell a horrible rubber/ petroleum smell that literally filled the room! Tried leaving outside in 40 degree weather for a few days and the smell was just as bad. Tried soaking them in a glass full of alcohol for 24 hrs turned the alcohol brown, root beer ish color. Smell was still there. Tried a second alcohol treatment and the next day the alcohol was just as brown and the horrible odor was still there. People tell me that this is typical of Chinese rubber products. They went in the garbage and I'll never deal with this company again. If possible to give lower that 1 star I would!
