Good for price. Took me the whole weekend to build; 2- 3 days. Plan to insulate - hot AF now in June. Built a wood sub flooring. Happy with purchase.

Overall great for what we need it for. Definitely a pain in the rear to put together with 2 very competent people. Took over a full weekend. The instructions will have you questioning and be ready to take some steps apart to redo. The man door latch system is chinsy so it's not great for valuable items unless you upgraded that part. Good value for the price.

I took me over a month to decide on a shed ... Plastic or metal?? And the there's the Price ... $500 or $1500?? I decided on this shed which was offering $100 off, but it wasn't a Prime item so the shipping was $100. Still I got the shed at the price I wanted to spend on a "metal" and the size I desired. 10X8. The metal is decent. There are some gaps upon completion but I think I'll caulk it to fill them in to make certain it will be water proof. Here's some tips: -if you're building your own base as I did, make sure to make it AT LEAST, 98" long and 105" wide! Or else you will be short! -take your time ... there's no quick way to install 600 screws. - USE A MAGNETIC TIP on your drill bit or screw driver. You will have to hold panels in place while screwing them tight. A magnetic driver will save your sanity!! -the metal is a little thicker than a beer can. It's a doable shelter for your tools, DON'T COMPLAIN IF YOU DIDN'T WANT TO SPEND MORE $$$!! -DO NOT BUILD ON A WINDY DAY ... you will become frustrated!! -OVERLAP All panels to make a "Channel" for water to run down. You will see one end of every panel is somewhat flat and the other side is "U" shaped. Put them correctly to make a channel! All in all I recommend this shed and building you own base. I did this ALL BY MYSELF ... It took me 10 hours from start to finish, so PLAN FOR THIS TO TAKE YOU ALL DAY! And be happy when it's done, don't go back on Amazon shopping for another shed, and wonder if you could have gotten a better deal ... Just enjoy what you have built!

I like the building but the instructions are horrible. The video pretty much useless. Don't expect to build it in a day, or even a weekend. You will need help a couple times. The panels keep changing direction. There is no left right up down in out instructions on any pieces. A couple stickers here and there could save so much time. I wrote repeatedly asking what dimension I needed to make the floor, so I could have it done while waiting for shipment. Never got an answer and I believe it's because no one ever put one together that works there. Oh it's not 12x20. I wanted floor the same size as the building, so water has no where to sit or run under these sides. Go buy some 3/4 inch self tappers before you start. You will need some. I bought some 1/2 and 3/4 to have on hand while building. I really wish the windows were sliders. The lock is a joke. There is no latch to hold the side door closed. I would prefer to open the front doors from outside, but you have to go through the side door to open front doors. They don't include a floor plate for the front doors to lock into. You can't change the location of the side door. I know it's a surprise I give it 3 stars but I am so happy with the size. Yes there are things that could be better, but come on a wood building is 5k for this size.

I figured I would wait a while until I review this shed. I paid around $1300 for this 12x20x9 shed. It went up fairly easy with one person a majority of the time. There are steps when two people are needed. The instructions are terrible. They are not easy to follow at all. I would say it’s actually pretty sturdy once assembled. However during assembly the outer parts of the frame are very flimsy. A majority of the framing is made of galvanized steel. The outer roof pieces are aluminum and very easy to strip out when screwing into. The shed looks far better than it actually is. I’ve been fighting leaks non stop. It should almost come with some way to seal panels because the small Phillips head screws do not do the job. I would have much rather spent the money towards a stick built shed. The doors seem to sag as well and the latch doesnt line up for the door half the time so it’s hard to lock. Save your money and build a wooden shed or find another kit.

I was planning to set up a home gym in my garage, but I had too much stuff and needed extra storage space. Instead of going for a wooden shed, which was quite expensive, I decided to buy this stainless steel shed and so far, I have no complaints. Of course, it’s not the same as a wooden shed and isn’t as naturally sturdy, but once assembled properly, it works really well. I added a few 2x4 supports myself for extra strength, although it was already decent on its own. The most challenging part of the setup was dealing with the large number of screws it took me a couple of days to fully assemble everything. My recommendation is to check the weather before starting, because even small delays can slow you down quite a bit. We recently had heavy rain, and I noticed there was no leakage inside. It held its shape well, which was a big plus. Overall, considering the price and what it offers, I’m very satisfied with this shed. It served my purpose well and helped me move forward with setting up my garage gym

It held up during a hurricane, but it comes without floor, so it’s kind of flimsy when you try to move from one point to another

First off it’s a 20 x 12 shed but it’s actually 11’ 6” x 19’ 6” which sucks because the floor should match the shed. Contacted the shipper and they sent some ridiculous sizes when I asked for the dimensions. The Good Large shed for the cost Looks nice After many many upgrades it should work The Bad The instructions are incorrect and almost useless. You will have to take pieces apart because they don’t explain anything correctly. Took 5 days total with 1-2 people to assemble due to the poor instructions and packaging. Most parts come covered in a super thin shrink wrap material which does NOT come off in solid pieces. Took probably an entire day just to remove this before installing and it’s still scratched. The panels came damaged with holes, dents, contacted the manufacturer like the instructions say and never got a response. The metal is THIN like a soda can material but once together it’s solid. The shed leaks because the hardware included is cheap and not sufficient. Had to caulk everything from panels to screws, used liquid nails on the roof vents and edges. Summary I would have just bought a solid wood shed kit for $3,000 to $4,000 that included the floor. It would cost double but also would be much sturdier and better quality. Floor cost $1,200 in materials alone.
