The sleek overhang roof design also prevents rainwater from gathering

  • Beautiful gazebo
Material Type: Wood Like Size: 10'x12’
Love this gazebo. Got the 10x12. Very sturdy. Took about 8 hours to put together. But well worth it. Instructions were very easy to follow and all hardware was included with extras. Holes lined up great. What a beautiful edition.

  • SUMMERTIME. NIGHTMARE
Material Type: Wood Like Size: 12'x14’
As far as the Gazebo itself I am pleased , but I WENT THROUGH TOTAL HELL DEALING WITH MELLCOM . THE DELIVERY SERVICE THEY USE IS CRAPPY AS HELL . After 3 seperate deliveries of the damaged , unuseable roof panels and a month of back and forth with Mellcom THE 48 HR WAIT FOR THEM TO RESPOND EACH TIME I RECIEVED ANOTHER SHIPMENT OF DAMAGED PANELS . THE PANELS ARE SHIPPED IN A METAL FRAME WITH NO PROTECTION TO PREVENT DAMMAGED TO THE PANELS WITH SARAN WRAP AROUND THE TOP AND BOTTOM OF METAL FRAME NOTHING TO STOP PANELS FROM SLIDING AND BUMPING AGAINST THE METAL FRAMES NO SUPPORT AT ALL , THIS IS WHAT CAUSED THE DAMAGE TO THE PANELS NO WARNING INFO LABELS ON BOXES ( do not drop , Fragile , etc.) One set of panels had complete boot prints all over the boxes where they had beenrepeatedly walked over . I HAD TO CANCEL MY BIRTHDAY AND 4TH OF JULY EVENTS THIS YEAR , It was to the point that I requested a full refund Mellcom refused , I requested compensation for shipping and handling that I paid Mellcom refused I after going through taking pictures of damaged torn up boxes of panels, damaged panels , proof of how they were delivered to my home Mellcom had the nerve to suggest that if I could make repairs to the panels if possible , and their cost for having to reship new boxes of roof panels as if it was my fault . " My response " I paid for shipping and handling and a BRAND NEW GAZEBO AND THATS WHAT IM EXSPECTING TO RECIEVE . FRUSTATED , PISSED OF AND HURT BY THEIR BUSINESS TACTICS . THANKS TO THE ASSISTANCE OF AMAZONS PISSED CUSTOMER SERVICE TEAM MY NIGHTMARE IS FINALLY OVER , AND MY BRAND NEW GAZEBO IS COMPLETE . ... show more

  • Horrible Customer Service, doesn't not supply replacement parts
Material Type: Wood Grain Size: 14'x20'
The product is very nice, easy to put together(you will need two people) and looks very nice. The reason for the 1 rating is more for the company MELLCOM. I contacted them about a replacement part of a post that buckled and was told it was out of warranty. I then proceeded to say I would pay for a replacement post and was told that they don't have any replacement posts and I should check with a local supplier. Seeing as I bought this from Mellcom through Amazon, I asked if they had any thoughts of a local supplier or even a part number that I could search the internet for and was told and I quote. "We sincerely apologize for the inconvenience. However, we humbly ask for your understanding that we do not have a specific link regarding the parts. We suggest that you hire a local repair service to replace the damaged post. Your understanding regarding this matter is highly appreciated. If you have any other questions or concerns, please message us." So I glad that they highly appreciate taking my money as I now understand I have a 4 post gazebo in my back yard with only 3 posts....wonder how understanding my guests will be if it falls on them. Great product, horrible customer service and ability to get a replacement part for a $2,000 gazebo ... show more

  • Not the easiest assembly but worth it
You'll have to use some critical thinking skills as the instructions aren't perfectly clear on everything, especially when it comes to when you should and shouldn't tighten down screws. For example, you'll never be able to tighten the footer screws after you stand the posts upright, so you have to tighten them right away. For the rest though you'll have to keep them loose until almost everything is standing. Use your judgement to tell when you'll lose access to a screw and make sure to tighten while you still have the chance. Seems pretty sturdy. Survived the winter storm we got just fine. (Didn't have the canvas up yet but it has straps attached to tie that down to the posts for when it's too windy.) Seller is helpful if you need to contact them. Do it through Amazon though. The email address on the manual appears to be an old one. ... show more

  • 14x20 gazebo
Material Type: Wood Grain Size: 14'x20'
Instructions are easy to follow for me I work in construction and have all the tools to make it easy might be a little challenging for the average person. I bought two of them to make a 14 by 40 foot shade, I was able to install by myself with the use of two 6 foot and one 10 foot ladder. You will need a helper for some of the roof bolts but that can be after installation. The framing is very easy it’s the roof that’s a little tricky, the holes do line up but you need a screw driver to Aline the holes I used about 4 of them. The only bad part of the roofing is the end brackets that keep the edge of the metal roofing in place (very poor design). All in all I love the way it came out very nice gazebo and I would buy another one. I live in Los Angeles so it should be ok for our type of weather. If you live in a harsh environment might want to consider something a little more stronger but still very stable. I gave 4 stars only because of the edging support brackets on the roof. ... show more

  • Use power tools. The enclosed wrenches would have taken forever!
Material Type: Polycarbonate Size: 12'x16'
We will be using the gazebo for a car-port. All the necessary parts were enclosed and the instructions were adequate, just take your time. The shipper dinged up a few of the roof panels, but not to the point of being unusable. I am impressed by the quality, the fit, and the sturdiness of the finished product. My most important tip: use an impact driver (or a drill with a slip-clutch) with a short extension and a hex bit to drive the screws and - in the many spots where the clearance is tight and you can't get a straight shot at the screw - insert the hex bit into the screw-head first then slide the driver extension on to the hex bit, rather than having the hex bit in the extension then trying to get it inserted into the screw-head. (Fussy, minor point, maybe, but it saved us a lot of stripped screw-heads!) All in all, a good product, good value, and a fun/challenging 1 to 2-day project. ... show more

  • Careful with panels for this product
Material Type: Wood Like Size: 10'x12’
Great product. Be careful on the installation the panels are extremely brittle. If there's malformed do not try to bend it it will snap. I don't understand why they don't have replacement panels but they have replacement curtains!?
