I ordered this item from amazon for a trip i was planning but it did not come in time before i was leaving, i was able to get the same exact one through Walmart on time same price. i was using this for a 550 mile trip to San Diego and back so it was 1100 miles round trip. every 150 miles i kept having to pull over because the tie downs would come lose and from the very get go I HAD tied knots in the tie downs so they would flap around and loosen but they still did. By the time i got to San diego the driver side support bar was showing signs of bending, but it made it to san diego and at that time thats all i was worried about. On the way back from the San Diego trip about 200 miles from home both support bars bent in , and the big round plastic elbows you see on each side of this thing,were laying on my hood and took out a "dime" size chip of paint out of my new 2010, 4 month old VW Jetta. i put towels under the plastic and made it home barely. DO NOT BUY THIS JUNK.
