Title: Won't use these again
Review: I invested hundreds in the whole Yakima rack, these rollers, a couple of saddles and a bunch of locks, and am not happy. Using the rollers with my 12-foot SOT, they spun on the crossbars when lifting the yak up there and gouged the top of my car. I see no advantage to these over the saddles, but, then, I don't like the saddles much either. Too much installation time, and they look goofy without a yak in them. Instead I stored the rollers and saddles in my garage and now use the foam blocks on my rack. They're not perfect either, but installation is a matter of minutes, they don't damage my car, and they're cheap (unless you've already thrown money at the rollers and saddles). I don't understand all the 5-star reviews here for these rollers. Maybe for small kayaks? Even then, doesn't make sense.
Is the review positive or negative?
