I would suggest putting felt pads on the bottom legs if you are putting it on wooden floors. These roof racks are easy to install and made of good quality material for affordable price. But youll make it work. Material could have been better for the price you pay but on the glasses market you wont find any that come close to the size of these. Pros:-Wow these are LOUD great bass and highs. Heres the thing: Its battery life IS truly long, and its sound quality is awesome! I get so many compliments! A couple years ago my Tevas blew out while I was on Cozumel and I found a pair of sandals in the local super market for $15. And having these buds in all the different colors is great since my kids fight over earbuds. As a German, I love Birkies.
