I bought the grey model. Wood on top corner of one side panel was split about 10”. I debated about returning and decided I didn’t want the hassle, so repair it with wood epoxy. Assembly was easy and the pre drilled holes aligned correctly. Installing the interior shelves was a challenge for one person, but I managed it — and I’m almost 70 with 0 DIY skills.
The wood is a very light, dry unspecified type of fir that is probably one level above cardboard, so this shed will have very short life if left outside. To prolong its life a bit, I applied 2 coats of Nano wood preservative. The wood slurped up the preservative.
I’m modifying a second unit by adding entry holes (on the bottom and sides) to create a cat escape shed to give my outdoor cats a place to escape dogs, coyotes, or other predators. Just need to figure out how to keep panels together once holes are since the panels are tongue-in-groove construction without any adhesive.
What about using wood glue on the tongue/grooves on that side?
Proceeds to talk about fixing with epoxy, assembly, applying wood preservative, modifications…
Hey, I talk about adding epoxy and making modifications but that doesn’t mean I know what I’m doing! My DIY usually involves duct tape and/ or zip ties. 
Yeah but… How much modification do you think I need to do to make it last outside in Northern CA for a few years? ! I’ve been looking at this for months hoping for a sale & t is the first time I’ve seen real details about the quality. There’s a lot of lookalikes (or are they the same?) from different manufacturers & I thought LC was one of the better ones. Now I’m torn. Thoughts?
I think you could get 5+ years if you apply a wood preservative or good exterior paint. Without some sort of added protection, I doubt the wood would last 2 years any area that gets rain.
The finish on my grey shed offered no weatherproofing at all — the wood sucked up the wood preservative without any cleaning/stripping required.
I also suggest setting the legs on bricks or blocks of pressure treated wood so the legs aren’t in direct contact with soil.
