  • Amazing structure and price
Great structure! I bought this to replace the existing one that I built by hand 5 years ago and I got to say, this was such a easy install! The whole system came in 3 big boxes. Everything was packed really well and labeled in alpha letters with written instructions so it was easy to identify and put together. Everything was put together in a matter of about 2-3 days with 2 people. All screws and pieces went in great and all aligned up. I didn't have to modify or adjust any holes. Overall great product and was well designed. It looks great once it is done and seems sturdy as well. You can attach it to the wall for added stability and it came with all the necessary brackets to do so. Very impressed and glad I bought it. Recommended! ... show more

  • Some hints
Color: Dark Size: 14' x 10'
I am writing this review for the 10x14 model. Over all it looks okay, doesn’t shade as much as I had hoped but again okay. Assembly wasn’t hard, did it by myself with a ladder and a DeWalt cordless drill set on low torque. I will share some things I learned along the way. I wanted this to fit under my eve's' so I had to cut about 3 inches off the legs. I used a chop saw and a drill press to accomplish this. About the assembly itself; DON’T LOSE ANY BOLTS OR NUTS; they didn’t give any extras of anything. This would have been nice, since a couple of the nuts were missing threads. Luckily I had some nuts that fit. The bolts are cheap, heads strip easily (even by hand). When mine was manufactured the quality control person must have been on break or didn’t care. There were a lot of “punch” tabs left in the holes and almost all the threaded holes had paint in them, making it hard to put together. After I started checking the holes (before assembly) things went a lot smoother. The frame was easy to construct, the instructions (which is just pictures with few hint words) don’t tell you to leave the bolts for the “arm and beam connecters” (brackets) finger tight. Leaving them finger tight makes installing the pp boards easier, then you can make adjustments to the arms as needed. The next issue is there is a paper in the box with the pp boards that says not to remove the protective film before assembly, which is wrong. I did that for the first 7 pp boards, it was a nightmare to remove the film. Ended up taking the boards back out to get it all off. When installing the second set of pp boards I took the protective film off each before installing. I had to use a couple of putty knives to get the boards in the middle board connector slots. I found using soap & water in a spray bottle let them go together much easier. I may have put them in upside down, don’t really know the instructions only tell you to make sure the “leak” holes are up. I put the wide side up; don’t have any idea of how I would have ever gotten the boards in the slots if I did it the other way. Even after attaching the frame to my porch posts it is still a little wobbly. I didn’t attach the roof to my house, wasn’t willing to drill holes in my siding. The braces that go on the front legs are sufficient, but could have been a little bigger (might have taken some of the wobble out). Also a couple of braces on the back leg might have helped, think I’ll look for something to use for braces. Over all might buy again. 1. No written instructions 2. Don’t lose parts 3. Check for punch tabs and paint on threads 4. No back let support if not attached to the house ... show more

  • Caution, only for a confident 'do it yourselfer"
I gave it a 5 star for the structure but only 2 stars for the instructions. Once assembled it is a sturdy and attractive structure but be aware of some challenges. We purchased an 8 x 16 unit for our back deck. First and foremost, the directions are only diagrams, and you have to look very carefully at the diagrams to notice how to assemble, the only 'brief' written instruction was not understandable as it was a poor Chinese to English translation. Caution, you have to assemble the entire structure BEFORE attaching to side of house. For our large unit we had to use some temporary diagonal cross braces with clamps to keep it steady until bracing against house. I noticed some reviews complaining of leaking; I attribute this to the panels not completely installed into slots on cross pieces, as this was the most challenging part of the project requiring two people as the panels required some light tapping with a rubber mallet to seat into the cross pieces while your helper guided the panel into the slot, but once installed were super tight with no leaks. ... show more

  • Spend more and get something of better quality.
Color: Dark Size: 8' x 8'
Where do I start? Scuffed/scratched pieces (could have been from shipping), pieces not labeled, crappy materials and poor instructions! I've included pictures showing what the panels look like with the protective sealing still on. One of the seals on one side is white and quite frankly that's the only reason you can't see through this thing at the moment. It will provide no shade whatsoever; which is kind of the point of this product! Also the panels are cheap plastic and flimsy! In the first picture I put it next to a cardboard box that came from Amazon. You can clearly see how crappy it is! The cardboard is thicker! The gazebo itself is just a bunch of smaller pieces that you have to combine together to make larger pieces. What I mean is that normally a gazebo will have four posts and those posts are all single pieces. Instead you will have to put together five pieces to make one post! Two of those pieces are flimsy feet pieces that can't really hold anything in a balanced position unless you anchor them into concrete. I suppose the company did this purposefully so they could easily ship this in comparison to a much more quality gazebo. This is also the same for all the roof support pieces as well. Each roof support is four pieces instead of one! They say that this thing will not leak, but there are so many little areas for openings it's ridiculous. Water can squeeze through the tiniest of cracks, so it's definitely going to leak through this gazebo. After seeing reviews from JMore332 and GBee where it's completely collapsed, I've decided to return this rather than opt to put it together and be even more disgusted with this purchase. For a gazebo to collapse like this with the possibility of people underneath it is an extreme safety concern! ... show more
