It is laughable that they’re allowed to sell this. The shed is an example of someone designing a shed without actually ever putting it together, in theory it’s great. Just clip the sheets together, slip them into the top and bottom bracket and presto you just slap the walls together, put the roof on and there you have a shed. 
In reality, the sides when clipped together, are impossible to set into the top and bottom brackets because the metal is barely a step above tinfoil and even the gentlest attempt will result in the rolling of the metal making it impossible to actually assemble it. 
Waterproof when assembled Like a sieve. 
Speaking of assembled, the only way I was able to was build my own foundation and wall brackets and screw the metal onto the wood directly in order to try and salvage this godforsaken trainwreck that’s marketed as a shed. ￼
