I got this for my very spoiled lovebird and I couldn't be happier with all the space. It's designed well and has a good layout of doors and access points. It looks sleek and I love the cart for mobility and storage.You do get what you pay for, though. The cage is overall quite durable but the bars are somewhat flimsy. This isn't an issue for smaller birds but I could definitely see larger parrots damaging it. It arrived with some bent racks, broken trays (seller quickly replaced these) and imperfections in the metal. The biggest worry were the few metal spurs I found on welded joints but they were easily filed away.I got this cage with the intention of leaving the divider out but the size of the gap that is left without it concerned me so I had to improvise. I used some heavy duty vinyl strips left over from putting in new windows to fill the gap. I cut them to the proper lengths and used zip ties through the bolt holes to secure them. It works great but I will have to cut the ties if I ever want to use the divider or move the cage.By far the WORST part was assembly. There are no directions and after lots of googling with no results I ended up having to wing it. The longer bolts are for the cart portion. The cages themselves only use the small bolts and it's pretty straightforward assembly. I recommend sorting through all the parts before assembling anything. Make a pile of one cage front, one back, one side, one top. The side piece has a door for a breeding box towards the top. Use the bolts to attach the front and back panels to the side panel and then attach the top. Do the same for the other half of the cage, just mirrored so you have a right side and a left side.The cart was a bit tricky to put together on my own. I highly recommend getting help for this part so you don't end up balancing panels on your head like I did -.- Take a few minutes to lay out the pieces before starting so you can figure out the best strategy and which of the longer bolts you'll use and where. The racks go on the bottom and I ended up having to use one long bolt to fasten the left rack, center bar of the cart, and right rack together.Once the cart was assembled I put the left and right halves of the cage on top and slid in the grates and trays. This is where you'll have to figure out if you want to use the divider or find a way to close the gap. You will have left over bolts and bits. I put those and the tools it came with away for safekeeping should I ever need to reconstruct this frankencage again.That's about it! I love it, my bird loves it, my wallet loved it and two months in we're all still happy. Well worth an afternoon of cursing XD
