The edges let too much light in not truly blackout. I asked about balance as well and they don't have one. Just not great at being blackout Cause the sides

Hello Tyler, I have just sent you an email so that we can look into this issue for you and get you taken care of. We want to make sure you are satisfied. With an inside mount, there is always the possibility of some light seepage, due the to automatic inside mount deduction that is taken, in order to ensure that the fabric does not rub against the side of the window opening. We appreciate the feedback and I apologize for the inconvenience.
