This product is cheap and cheaply made. One of smaller beaker shattered after surviving a 4'9" fall when a 22oz Eastwing hammer fell on it two days later which fell the same distance. It also didn't come with any warnings that if it breaks shards of glass could injure you. So I figured it was safe to walk barefoot with no regard of a careful immediate clean it up. So I had lost two weeks of pay do milking my injuries. I believe compensation should be paid for since there was no warning label stating that if broken shards of glass will injure you if not carefully cleaning it up. Yeah, I'm not that guy, these are definitely worth their value.
