  • Good Value Shade

    We bought this to shade part of our pool from the intense Texas sun. It's still spring but it is already doing a good job. The included hardware was poor quality but I expected that based on reviews from others. Installation went well after picking up some good turnbuckles and anchor bolts from the hardware store. This product is large and awkward so plan on having a couple of able bodied folks on hand for installation especially if stretching it over a pool. Given our available mounting locations, we weren't able to mount it with 2 diagonal corners higher than the others as recommended in the instructions. This led to a sag in the center with our installation due to the size/weight of the product. It stood up to some big winds but seemed ready to "take flight" so I'd recommend taking it down if high winds are expected.

  • Adequate Shade

    This shade does provide an adequate amount of shade but the product description is misleading. It says the dimensions are 18x18 when in fact that is the possible dimension it can be stretched to, at least that is what I was told by the customer service rep. The square shade went up as shown however no matter how much tension we put on it even with a pitch allowed for rain, dew, etc it still sags in the middle. i am thinking overall the traingular ones would have been a better buy than the square. The sagging in the middle drives me crazy not to mention that overall it is not good for the fabrics longterm wear.

    • How did the color on site compare with the actual product? the color was right on target
    • Please tell us about the quality of the product. quality appears to be good
    • How accurate was the on site description of the product? not quite accurate
  • Great Shade, Dangerously Horrible Hardware

    Do not underestimate the poor quality of the included hardware, especially the turnbuckles. Unlike some other reviewers, I went ahead and attempted installation with the included hardware. Without even reaching the necessary tension, one of the turnbuckles failed completely, with the eye bolt slipping right through the turnbuckle body. Local hardware store sells stainless 5 1/4" turnbuckles for about $5/each. The shade itself is very nice and appears to be good quality, but they sure dropped the ball on the hardware and would have been better off not even including it.

    • Did the color match the color displayed onsite? yes
    • How is the quality of the product? excellent, except for hardware
    • Did the description onsite accurately describe the product? yes
  • True Test

    Two weeks ago we had a bad bad storm come thru our area, our shade sail is hung under our soffit with heavy eye bolts and off the house I put in two 6x6 post concreted in the ground with heavy eye bolts too, well the strom came thru and we had 80 MPH winds I was worried stood at the door and watched the shade sail it just waved in the wind I was amazed with stood 80 MPH winds great product but I would also say it was anchored very well too. worth the money only downfall it you still get some of the hot sun thru it.

    • How did the color on site compare with the actual product? Good
    • Please tell us about the quality of the product. Outstanding
    • How accurate was the on site description of the product? Good

  • Great for schools

    I purcahsed to of these sails for our playground. They were very affordable. Our handyman installed them with a helper. It was definitely a 2-man job. He replaced the hardware with a better quality and the ropes with steel cables because we were concerned ablout wear and tear. The sails look great and provide cool shade. The children and staff are enjoying them.

  • Loving it on the patio

    Very nice product my ONLY criticism is I wish it came in a bright orange color. The yellow is fine but I would have preferred something brighter. It looks great and functions just as it should.

  • Read the dimensions!

    I misread the dimensions which are given in meters not feet! This is huge and we have no place to put it but it has been opened so I can't send it back. The quality looks good if we had a place to put it!

  • NOT waterproof

    I ordered this item because I though it was waterproof but it was not. Therefore I will be returning it shortly. However, it was nice material and really well made. Great buy if that is all you are looking for.

You can't ask the manufacturer if it is fire rated? This is all I need. Simply question to ask. It say UV rated. What does this entail?  on Aug 31, 2012

Three part question: 1) Does this shade have nylon webbing the full length of the sides, or just at the corners? 2) Is the low density polyethelene (LDPE) woven or knit 3) can you describe the weight of the ldpe on a per square meter (or square foot) basis, as seems to be the standard in australia, where these things originated. Thanks.  on Aug 8, 2012

the sail says it is adjustable from 16-18 feet. if it is installed parrellel to the ground how much space will it cover? chicken835 on Jun 21, 2012
Subscribe to Answers
Answer This Question

This is a response we received from our distributor The question does not have just one correct answer once we think about it. Here are the facts and why: 1. The sail itself is NOT adjustable from 16-18’ to start with. Measured from corner to corner it measures 5.40m or 212 5/8” or approx. 17’ and 8 5/8” 2. Being a square all sides are the same 3. The problem though are the curved sides being part of the, which under correct tension will leave and approx. net area of around 21.3 square meter or 229.2 square feet. 4. Yet the gross area required to fix it would be much more due to the shape and required turn buckles to fix each corner which will add to the overall area. Hence the minimum gross area required to fix it would be around: 5.55mx5.55m = 30.8 square meter or 331.5 square feet. As people are generally asking about the shadow area under the sail (the whole point I presume), the biggest problem/variable for the shadow area underneath the sail when mounted parallel to the floor is the anglel of the sun and the mounting height. As the angle of the sun changes from nearly 0 in the morning, to depending on where on the planet to up to 90 degrees on the equator line (where I believe the US in not located ) at noon and back to 0 again, thus changes the projected area of the sail in the same way. Hence, there is not just one correct answer as he area changes dramatically depending on the location on the planet, the time of day and the height the sail is fixed. Hope I did help at least a but rather than creating more confusion  overstockcustomercare1 on Jun 27, 2012
