We bought 2 of these in white for our kitchen, which has 2 very large windows right in front of the table and chairs. We raise them every morning, all the way up so they're hidden behind the valance, and lower them all the way in the evenings to block the sun, and for privacy from the neighbors. I waited over a year to review, in case problems turned up. NO PROBLEMS at all, and we love them as much as when we bought them. Just make sure you always use the center tab when raising and lowering, and they'll stay straight. Also, make sure you don't get food splatters on them, if they're going in that kind of area. Dust vacuums off easily, but grease and food stains can be tricky.
