I purchased these crossbars for my 2022 Kia Niro.Assembly was fairly easy but the directions could be clearer. I did have some trouble getting it together because of tight fitting parts. Once assembled they went on easily but the pads are not glued on so they may come off while installing. I believe they look good on the vehicle.Once installed, I took it for a test drive and there was some slight whistling but the radio covered it easily. I did notice a bit of a drop in mileage but that is to be expected.Over all, I recommend this product.First of all, if you order these and have trouble figuring out how to put the end caps on each rail, the solution is to use the included smaller hex key to loosen up the screws that you'll see on the end cap assemblies. That will give you all the wiggle you need to slot things into place without needing to use a mallet.I got everything onto the kia and tightened it all down. Seems snug and secure. However starting around 40 mph there is a hum/whistle of wind audible from inside the car. Usually the sound goes away around 60 mph, but sometimes it's still there even at 65/70. I think this may have to do with the small gaps along the inside edge of the rail created by the way the end caps are secured to the rail. These gaps create 4 wind tunnels, and the excess screw lengths create more surface area for friction/noise.I don't have a model with sunroof and can hear it inside the cabin with all the windows up. If I had music on a medium volume, it might drown it out. However it is definitely a noticeable hum/whistle and it's loud enough to make me question keeping this (though not really sure if other options will be any better).Much cheaper than a Yakima rack, which was not in stock for my model car. Despite being extremely mechanically inclined, it took me many hours to assemble the four side brackets, which in the manufactures video look like they are supposed to slide on effortlessly. I spent a lot of time trying to muscle them into the cross bars and they would always get stuck half way. Each time I tried, plastic would peel off the insertion probes of the brackets. I emailed the customer service department and after 32 hours there was still no response.Eventually, I realized I could disassemble the side brackets. This made it a little easier to inset into the cross bars, but they would still get stuck. But at least I was able to see where and why they were stuck. Eventually, I had to shave off bits of plastic on each piece in various places. It was almost like trying to fit a square peg in a round hole. Eventually I was able to insert the plastic into the bars and reassemble the brackets. I still have yet to mount them to my car, but I think they will work.UPDATE:Only now am I realizing that I made a mistake with the brackets. They do slide in almost effortlessly, if you insert them on the opposite side of the bar. I disassembled them and reassembled them correctly. Perhaps the instructions were not clear enough, perhaps it was user error from the start on my part, who knows? Maybe I am not as mechanically inclined as I thought.Since I have not installed them yet, I will update again soon. They look like they are good quality racks. Despite my set-backs, I have high hopes.SECOND UPDATE:Customer service did get back to me after 48 hours to confirm that I had made a mistake. The racks were already fixed and installed. So far, I am happy with them.Had I not made this mistake, I think I would have assembled and installed these racks in less than an hour, perhaps less than 30 minutes.I will update after I use the racks. So far they look good and sturdy.THIRD UPDATERacks work well. Very sturdy. No wind noise. They have been up for over a month.Difficult to insert the crossbars into ends. Had to put them into a vise and hit them with a rubber mallet. Not sure how far I should insert them. Also included were two Allen T wrenches of different sizes, The larger size is to clamp the bar to the roof rack, but the smaller one is to adjust what?Also one of the pads that go on the clamp (the smaller of the two on each clamp) was missing. How do I ask for a replacement?It seems to be of high quality and I look forward to using it once I get the missing pad.Will BrownAs a 55 year old former triathlete, track, cyclocross, and road bike racer, I have had several major brand racks on several cars. I have also sold Thule, Yakima, and Performance racks when I worked as a bike mechanic.This is a FANTASTIC value: a solid set of wing shaped aluminum bars, rock solid mountings brackets, the option of standard track nut/bolt mounting, AND includes a set of lock cores!A good set of instructions and one of the easiest installations I have ever done on any car (in this case, my KIA Niro.) It also does not block the sunroof and is not very noisy, even directly over the open sunroof.The track gasket is a rubber tube, so track nuts or bolts can slide in and out without cutting the gasket.This should be the wholesale price.This is made in Turkey to European Union standards and it shows in the build quality.Installed in about 20 minutes. They seem secure. Easily handled bringing home a 2x10-8, furring strips and an 8' step ladder.Fit our 2021 KIA Niro well.Installation is straight forward, don't over-think it. Since the KIA roof rails are not quite parallel, plan in advance where you want to install. If you leave the ends wide enough to clear the roof ribs, then tighten the outward facing screws alternately, everything seems to settle in well. Snug up the upward facing screws when you're done.As expected, they do make some noise when the sunroof is open.The installation complaints here must have been faulty product?Disclaimer: I'm a mechanical engineer, which may have made installation easier.This racks have high quality construction and fit very well. I installed them in 30 minutes out of the box and are solid, look great on my Niro Touring SE.
