The blade sheds small black particles into food. When you pour some water and blend on high, you'll notice a Teflon-like black specs floating in the water. I've purchased two containers and they both had the same problem. The manufacturer is aware of the issue. I just wish they worked faster on resolving the problem with their jars as their blenders are very powerful machines and would love to use them in our café.
