CAUTION ! ! !    I have had SIX of these fail within 2 years. The shade's fabric separates in the sun and they SYMPLY FAIL .  And I hardly raised / lowered them - they just come apart in the sun.  I loved them as they look nice and are easy to operate. But I would be careful. Maybe I got a bad batch. Wayfair said they couldn't help since it was more than one year . . . so they gave me the manufacturer phone number but I doubt I'll get anywhere.  CAUTION ! ! !
