Sunair uses the best brand of motor in the business (Somfy systems). The few problems consumers may experience with retractable awnings are frequently with the local installer. Installed properly, fabric telescoping (what Gary mentioned back in 2010), and motors not stopping are not typically a Sunair issue.
It is possible, though, to get more use from a deck or patio by installing a retractable awning. There are two basic options for homeowners who want a deck or patio awning, said Ido Eilam, the chief executive of SunSetter Awnings in Malden, Mass., manual or automatic. Manual awnings must be hand-cranked open or closed; automatic awnings use a motor to do the work, but are more expensive. Mr. Eilam said that about 70 percent of SunSetter awnings were sold directly to consumers and that a homeowner with a minimal amount of skill should be able to install an awning in a couple of hours.
