Wash them first.
Well for the price, you get what you get. When I opened the package, it smelled weird, like weird weird not plasticy weird, so as i do with my old blenders, I washed all of them before use, but they all seemed to have some kind of yellow liquid coming out. It took multiple washings until the water came clear, so beware of using these blenders without washing them first.
