They are fine, but make a nice car look like Sputnik when left on as recommended.  It's a bit worrisome that it's so easy to crossthread a screw and ruin the receptor for good, but that's a design flaw of the cars using these, not the Yakima product.

I wrote this review to mention that you get four endcaps for the bars in the landing pad box, so you don't need to buy them separately.  I did, becaue the bars clearly did not have end caps, and now that I finally (delayed a few months) put the system together, I can no longer return the $10 end caps.  Just a note to skip the endcaps and see what you get when the landing pads arrive.
