    • Easy to Assemble
I put this together with the help of one other person in an afternoon. Took about 2-3 hours. Many portions can be done singly but very helpful to have a 2nd set of hands and strength especially when assembling the side panels to the floor. The instructions were very easy to read and understand. Just needed a screwdriver to assemble. Honestly can't boast enough about the simplicity of putting it together. Plus, it's holding 2 adult bikes, 3 kids bikes and 2 kids scooters. It's a tight fit but works! I haven't had it long enough to speak to the waterproof aspect but highly impressed with the quality and ease of assembly. Highly recommend!! ... show more

    • An Impressive Horizontal Shed
For additional yard-care equipment storage, I needed just the right shed to accompany a fairly large standard type of shed I'd built years ago from a pre-cut kit, rather like assembling a 3-D puzzle. (The wood wasn't the best, so I'd never do that again.) I spent hours looking at the multitude of possibilities online, finally settling on this one. The sliding roof was a definite attraction so that I wouldn't have crab into it hunched over. This one turned out to be just what I needed. With careful arrangement, it contains a limb chopper, corded electric lawn mower (backup now), a more powerful battery-operated lawn mower, a good-sized two-wheel wheelbarrow, and a very sturdy yard wagon, with room for a few smaller items that can be tucked in. The instructions recommend building it on a wooden or concrete foundation, which I certainly understand, but I used very carefully leveled 12" x 12" x 2" masonry blocks. I say carefully leveled, and I'm not kidding. It took some doing but I did it, anchoring the shed floor into those blocks as if it was concrete. It is very firm and stable---and was a lot less hassle than pouring a concrete pad. It did take great care to do it right, however. The assembly instructions were pretty good (I could have suggested a couple of improvements, but nothing serious), allowing me to do the whole thing in good order without delay. I also did it by myself, although two images are depicted in the instructions for a couple or three parts of the assembly. Anyone who is of at least average strength can likely do it him/herself. It all fits together just as the directions suggest, although sometimes it requires a little wiggling and jiggling to get things to set into place. (That's OK: Who want's a loose fit?) About that sliding roof. One name-brand similar shed I looked at---it also had a sliding roof and was more expensive--- looked pretty good until I read the reviews. Quite a few marked this one down for having a sliding roof that was not very easy to slide. I'm very glad I got this one, because the roof never fails to slide with complete ease. I've had this up for about 3.5 months now, through some heavy rain and blazing south Texas sun, and it exhibits no signs of warping or deformation at all, and I have detected no moisture inside even when, as happened a couple of nights when it was really storming, the wind was blowing very briskly. Sheds are not really designed to be decorative set pieces (unless you decide spend big bucks, but why not get a fancy bird bath instead?), but it looks just as a good and well made shed should look. I should mention that the doors properly close with no difficulty, the locking mechanism aligns properly with no manual acrobatics necessary, and it is at least as good as one might expect to get for the price. One final matter. Consider getting this lock, which fits perfectly: Master Lock Magnum heavy duty outdoor padlock with key, weather-resistant body and cut-resistant shackle, #M115XDLF, selling on Amazon today for about $14.50. ... show more

    • NOT GOOD FOR MY RIDER
I thought that this would be perfect for my Cub Cadet riding mower and I could free up space in my larger shed. Not so much. There is no way to drive it in and have room to get off the mower. This meant disengaging the transmission bypass lever and pushing it in from the rear of the mower every time. Getting it back out was a whole different animal. I am a 68 yr old smaller woman and I suppose I could do that but I don't want to risk slipping and or pulling something and with my closest neighbor being 1/4 a mile away it's not worth the risk. but it's up and staying up. I just transferred some other stuff out of the big wooden shed and made room for the cubbie, it's all good. It was easy to put together outside of the floor that's in 2 pieces I had to have my neighbor help me with it, while I stood on one piece he shoved the other piece into place. The rest was a one woman job. It's really sturdy as well made well worth the money just not wide enough for my mower. ... show more

    • Surprisingly Roomy and Efficient
Easy to assemble. Sturdy and perfect for what we need it for. This is a great supplement to our larger permanent shed. It fit perfectly under our deck. Don’t really need the sliding roof feature, but good to know it’s there. Was able to fit 3 E-bikes, lawn mower, Air compressor, Power washer, deck cushions with plenty of room to spare. Will rotate Winter items in the Spring. Very satisfied purchase. ... show more

    • Weathered proof storage unit
The outdoor storage unit is very sturdy and weather proof. It withstood some strong winds and torrential rains this winter. No leakage. Assembly was easy to put together. It took my dad and I about 2 hours. It's very spacious. Though I wish I ordered one that was taller. Overall great purchase 👍

    • Easy to assemble.
Pretty sturdy. Had to use Vaseline to get the sides to interlock. Use 10 redheads instead of 6. 2 on each end incase it gets a hurricane. Roof slides well and plenty of room for a 2 h.p. pump, 300 pound sand filter and plenty of extra space in the back and for me to walk around them. If you use redheads a hammer drill is best. ... show more

The media could not be loaded. Sturdy shed that fits a 30’ Craftsman lawn tractor well. I’d give it 5 stars overall. I agree with other reviews that there were a few alignment issues, but those were easily resolved with a rubber mallet. Very solid once assembled. I put it together on my own, which added some time, but the instructions were clear and the overall assembly process was straightforward. ... show more
