Apex Side Rail Mounted Aluminum Roof Cross Bars - Universal up to 50"

Vehicle: 2005 Jeep Liberty Sport (3.7l V6)I purchased this product to fit a Jeep Liberty roof rack. We purchased a Yakima Big Stack Kayak Carrier (http://www.amazon.com/Yakima-BigStack-Rooftop-Canoe-Surfboard/dp/B0012SFGW6/ref=sr_1_1?ie=UTF8&qid=1406410918&sr=8-1&keywords=yakima+big+stack) and also a double wide hard box cargo carrier.So far, we have driven about 4000 miles with these cross bars and they have worked flawlessly (we moved from Anchorage to Tacoma at about 2600 miles, then went on a honeymoon road trip from Tacoma to south central California and back). Here are my thoughts:Pros:-The bars felt sturdy upon taking the out of the package. The bars' sliding action feels snug and well designed.-The locking mechanism that keeps these bars from being stolen seems to do the trick. I am not sure how easy it would to simply break the locking mechanism off and take the bars, but so far we have had no issues with this.-The whirring, whistling noise when driving at speed is not as bad as I thought it would be.-These bars supported two 50 pound kayaks and some gear on a trip down and back up the west coast.-The ends of the crossbars that squeeze to grip onto your length-wise sport bars seem to grip very tightly. Careful not to over-tighten. The grip feels good and firm and does not seem to shift during transport.Cons:-The whirring, whistling noise. The noise these bars make at speed is determined a lot by what they are carrying. For example, our two kayaks were heavy enough to flex the bars a bit (but not to the point there was any damage or risk of damage to the product). However, the weight did make a concave shaped gap which made the whistling louder than with our hard box cargo carrier. Still, though, it wasn't loud enough to annoy or distract us, especially when chatting or listening to music.-The spinning/locking knob that tightens the product as well as locks them to prevent theft seems like it could be circumvented with a hammer or a crow bar. Then again, I am not sure how the mechanism works to the extent that I can say that a hammer COULD circumvent the locks.Overall:I was able to find these for $98 bucks along with a close-out sale on a hard box cargo carrier for $40 at Home Depot. $140 for the setup and it has lasted us literally 4k miles within the last 6 weeks. Very good product, albeit not perfect.My only suggestion is, if they can, try to find a way to prevent flex in the bars. With our hard-box cargo carrier, there was literally no flex in the product because the cargo box was centered and distributed evenly among both cross bars. However, our kayaks (100 pounds together) are carried only along one side of the vehicle (in our case, the driver side). This caused the bars to flex a little bit when our pull-straps were wrenched firm to hold the kayaks in place. This was NOT a problem and was not alarming at all. But a little more firmness in the bars couldn't hurt.Highly recommend this product. Very good, solidly built, and AFFORDABLE! A+
