We purchased two sets of these and used them on the Yakima roof racks on our pop-up camper. Assembly took less than an hour and attaching the 4 bikes took only 30 mins. We had two bikes (one youth/one adult) that had thicker support bars, so we just took apart the crimp assembly, placed it around the supports and then ratcheted them down like they're supposed to. We traveled 600 miles at highway speeds and only had one tire wobble. Overall, we are very pleased with the cost and performance of these racks!
At first it looked to high on my C frame... but after someone sat in it for 30 mins it stretched out so it's easy to get in and out of now. I added a few throw pillows which makes it's extremely comfortable now!
The view is a little fuzzy at 40x magnification but for 35 bucks it's not bad. I am not going to nitpick on that and I would recommend if you are not willing to pay hundreds for a spotting scope that you will use occasionally.
