European motor werke?

I was just wondering if any one has experience with "European motor werke". It seems that most of their products are sold on Amazon, but I'm not quite sure if this is a manufacturing company, or simply a seller. I ask because they sell what looks to be some good quality products, but at prices that are awesome. $65 shipped for brand new wheel spacers for example. There has got to be some kind of catch, right?



It seems that for the most part, the amazon reviews are positive, so I was just wondering if anyone here has experience with them.

Thank in advance
