Document: What a super retractable awning. well made ,attractive, relatively easy to install. This awning made our deck far more useable. We live in north carolina and the sun is very strong so having a place to sit in the shade when we want to is a blessing. Great prodsuct would recommend to friends. Also one of the most affordable retractable awnings I have found.
Everything I expected, even though it was 1/3rd the price of the more advertised awning. Maybe not the quality of fabric, but time will tell.
We had been looking at awnings that were 6 to 7 times more expensive. Then we saw this and read the reviews and decided to go for it and are sooooo happy that we did. We did have it installed for us and even with that cost it was much less expensive. It is easy to extend and roll up and the light color will not fade from the sun. It is also rain proof, but usually we retract it during our rain storms as they are usually accompanied by hail and wind.
this company is realy good i broke one arm on left side and did a complaint about it , and they send me both arm , very good now i got one as a spare in case. THis awning work perfectly ,,,
We have had it up for 3 months now without any problems!
