The assembly instructions aren't the easiest to follow using only pictures rather than a combination of pictures and words. I found my way through by trial and error. A previous reviewer's tip was to put the nuts in place before trying to screw into them and it was easier that way, I would add to that to thread a nut onto a bolt turning a couple of rounds to hold it whilst you locate it. The barrel took a bit of pushing down to get the shape to locate the last couple of screws.
The door isn't the best design, again, words in the assembly instructions to locate it properly would have helped. Instead of 20 mins it took over an hour and much head-scratching to assemble.
I have discovered you need to ensure the door is properly closed when you have put stuff in the barrel or it will deposit your veg peelings on your feet when turning the barrel. Again, the design could do with amendment.
It's too early to comment on the compost this makes but I'm hopeful it will be good.
