These flip flops were just worn around the house. This does create some road noise that you?ll notice (because any roof rack will), but not enough to make me remove these. In all fairness maybe it wasn?t properly locked in place but I didn?t want to be too forceful for fear that I?d break it. Quality piece of kit. The sound is a little tinny but acceptable for my purpose. Thats how comfortable they are. but other than that I would recommend this to anyone, and like I said, Im getting the X-Pad Slim for my new 17" laptop. recessed into the roof structure5 - Brand - while I ordered the "SNAILFLY" cross bars I had reviewed others, like the "HEKA" brand; I do believe it is the exact same product that will arrive to your door; when I was installing the towers to the rails I noticed there was some "HEKA" branded components inside the towerI may come back and update review should I run into problems, but these seem like a decent quality alternative to the OEM cross bars that are 2-3X the price It fits perfectly and protects. I have always dealt with excessive sweating under arm stains.
