I've been looking for a solution to my composting needs since moving in to my new place. Having an open-air kitchen and yard waste pile isn't very feasible for my neighborhood, so I've needed to find something enclosed. After hearing a handful of really positive reviews about this model, I decided to check it out. 

I'll plan to do another review once it's digested some matter, but until then, here are some notes on the set-up.

Bare Bones Instructions, Intuitive Assembly

First of all, the instruction booklet left a lot to the imagination. My instructions on how to use the composter are entirely in Spanish, but the description of assembly "steps" are in Spanish and English. My order was filled through Walmart, so I imagine that's a printing quirk rather than the company's intention--not sure though.

Either way, there are very few explicitly written out steps. Also, the panel with the sliding door on it seems to be depicted as two separate pieces in the instruction booklet, but mine came with the door already in the tracks (same for the vent covers).

That said, the composter fits together very intuitively. It looks intimidating at first, but basically you're just connecting pieces that look like they match one another. 

One of the explicit instructions says something about which order to attach your panels in. If you're like me, this makes no sense at first, but it actually matters. In the center right image of the collage above you can see what happens when you skip around with the panels. Basically you won't be able to fasten the bolts on the in-between panels if you do that.

And why does it matter that you do the door panel last? Because you're going to run into the same bolt access issue when you get there. You have to open up the door to attach the bolts, but if your last panel isn't the door panel you won't be able to fasten it. 

The bottom right corner image shows the track the instructions describe but that wasn't immediately visible to me. Just like the little latches shown in the center bottom image, you're going to be sliding each panel to lock into these joints before fastening it. 

I'm really excited to start using this one. I've been saving up yard waste to pair with kitchen scraps for the last couple weeks, so I'll definitely be able to report on production quality in the near future. Check back then for an update!
