These are nice shades but unfortunately the attachment to the window frame is not as secure as it could be - resulting in the shade sometimes blowing in and falling down if the window is cracked open while travelling at speed. This could be rectified with a few additional clips to keep the shade in place more securely. Given the price of the shades, providing a few spare clips it's not much to ask, particularly as it's highly likely some of the clips will be lost if you aren't using the shades year round. I did contact CAR SHADES to ask whether I could obtain some additional clips to solve this problem but didn't receive any response. Based on this issue and complete lack of customer service I sadly can't rate the overall product or customer experience very highly.
