We bought sun sails to put in our backyard and these ratchets made the sails taut without hurting our hands!

We bought this to replace a 12x12 we bought on Amazon 2 years ago.  That one was a different company and the corner's ripped out at the end of the first season, and by the end of last year's season we had to throw it away because it had large tears.  We have a rooftop garden in NYC and the wind can be wicked.

This brand has a longer warranty and seems to be better made.  The corners are stronger and the metal loops are heavier.  It looks great so far, but we've only had it up for a week.  Shade sails are great for city folks, where we're not allowed to put permanent structures on the roof without a permit.  The plastic lines that came in the kit are worthless.  We use turnbuckles and heavy duty rope.  You need to tie the sail as tightly as possible.  It reduces the heat significantly and looks nice.

Bought these before the summer of 2013 and put them up over my 20' x 12' wood deck in the Miami sun. It has now been over six months and there is no change in their color (blue), strength or purpose. The sail is a good product and recommended.

A friend let us borrow his for an extended sunny summer weekend on our sailboat.  We ordered our own as soon as we got home.

We bought the Petras 20' X 13' Rectangular Sun Shade Sail from Amazon at the beginning of summer.  We first tried buying the mounting hardware from the local hardware store, but we weren't finding the right pieces to make the job work.  We ordered this kit and it was perfect.  I should have ordered this in the first place when I ordered the Shade Sail.

Renting a place and wanted some privacy for our backyard without breaking the bank to put in a privacy fence.  This solved the problem, and doesn't look terrible.  NOTE: if you're installing a lot of this on an old fence, make sure to cut slits in it for the wind.  Otherwise, it will act like a giant sail and will pull your old chain link down in the wind.

Make sure you use big stakes and ropes to secure it. Mine has been up for a couple months. First stakes were too small. Rain water collected on roof in puddles. Added more tie downs and fixed problem. Works as boat shelter so far.

Took it to the beach, was OK under light winds, 5-12 mph.  Went to the beach house for lunch, sun was shining and a freak rain wind came.  Winds did not look that strong, many ez shade's were out with no damage.  I watched as the wind pushed the back side of the enclosure and both front poles bowed and broke about 4-5' above front anchors.  Anchored with sand bags so the shade house was fully secure.  Simply not designed for any wind conditions.

We love our sail shade. Cheaper and I think better alternative than having to  build something. It has been great during all theses pop up summer storms. No problems so far.

This umbrella is huge! Takes up half of my patio, which is great because we have 95 degrees and up days for most of the summer. It is not the sturdiest thing and will require huge patio pavers to weigh it down. I gave it 4 stars because in the spring we have pretty light winds (15mph) and the thing will sway and feel like it will take flight! I only open it when there is no wind. Other than that, you can't go wrong for a $90 purchase.

This is a great product and it was easy to put together.  It glides across my patio and I can move it to follow the sun.  This was worth the money and it has made sitting outside much more comfortable.

This shade sail works very well at keeping things cool on the south side of our house.  We have a large brick patio that was uninhabitable in the summer.  Now it is 20 degrees cooler with a nice air flow.  Seems to be durable after two seasons of use and the price was right.
