I used my vents on a trip recently and they have already broken in the corners. They are not rocket science to use, and they did the job, but for the cost of these I expected them to last for years, not weeks.
We apologize to see the vents have broken in the corners. We have looked into two possible reasons that have caused this and will be focusing on ensuring this does not happen again to future products as this is the first time we have seen any of our window vents crack and break as you had shown. We hope this will not deter you from any figure business and looking forward to helping resolve this for you immediately.
