As expected. Installation was a little tricky. First I got the wrong 'foot kit' for my vehicle on accident. Once that was corrected, the measurements in the included instructions were wrong for my vehicle. I looked up my kit online, found that there was a new version of the manual with new measurements for my vehicle. This turned out to be a closer fit but still not quite right. I had to 'widen' the measurements slightly... in order to allow the "doors" on the "feet" to close (these are the doors where you use the tool to crank down the brackets to your vehicle body to ensure a snug fit). Once completed, I'm happy with the product, just wish the installation instructions were a little easier to follow. There is an online video available through the 'thule fit guide' which was helpful but also not entirely accurate. I like this product because it is "modular" in the sense that when ski season is over, I can remove the attached ski racks and replace with bike/kayak racks.
You really don't want these on your car at eye/head level without end caps. First, I suspect they'll rust quickly (my old ones rusted even with end caps). Secondly, it's steel that's been cut with a saw- the ends are not jagged but neither are they gently rounded and the covering is shy of the ends by 1/8 inch or so. You hit your head/face on these things and there's a good chance you're coming away bleeding. Third, the ends are ugly without end caps.
Aluminium bars include T-track slots which allow you to use the full length of the bars for load carrying. The WingBar not only looks good but more importantly includes a device which reduces wind noise to the minimum, as well as reducing drag. Many customers leave their Thule WingBars in place from week to week, especially if they are taller vehicles and fitting is awkward.
