Wouldn't this be a warranty issue? If your TT is only 7 months old, I would think so. Blinds are okay, I'm just not a big fan of them. If it were me, I'd put curtains in. I put curtains on the windows in the bedroom over the day/night shades because it still wasn't dark enough when the sun comes up. They work great!! Just installed a simple rod inside of the valance and made curtains with a pocket at the top.
