I like this product and does what it is supposed to do. What I kinda wish is that it can somehow just stay in place while my windows are open.... it is inconvenient to have to physically remove them when they're no longer needed. they're also not that thick/durable. when I am not using them, i keep them in my trunk that has a lot of items tossed back there, i get worried that they'll break. they haven't yet, but I wouldn't be surprised.
