We weathered the unusual 75 mph winds a couple of weeks ago here in Las Vegas with an uprooted fence that had to be repaired, a flying patio table that used its closed umbrella for wings--none of those things had EVER budged before even in 50 mph winds. PLEASANT SURPRISE: our Eclipse Solar screens were COMPLETELY INTACT after the wind-storm, and even their fastening-clips were unaffected. This is a testament to the EXCELLENT work of Glenn, the owner and installer. Aw, shucks: we didn't have to call him in--bummer, man, my husband and I really like seeing this intelligent, charming fellow!
