FIRST FEEDBACK: This is how I got what I deserved: quickly looked through the options, saw that "these stocks" were cheaper than another set, and bought the product without to read all the small print . If I had read more carefully, I would have realized that the photo is misleading. There is only one camp, not ten. So they say, but it's hidden in the text. The photo should be changed to reflect the fact that only one bearing is sold here. Aside from the borderline (or not so borderline?) scam, the product appears to be good. But that's a pretty big digression. EDIT 8th July 2013: I now see the image has been updated to show a bearing. I will change my rating to four stars - this is a great product and now they fixed the part that was bugging me.
