Some mentally sick troll I'm sure designed it to laugh at me during the 8 hours of assembly! I have assembled dozens of things, but this was deliberately made for endurance and self-assessment testing.
Dozens of times I saw it shining in an iron bucket to take my revenge, but my wife, a gentler person, encouraged me...
About 400+ screws, an allen wrench that cut my fingers, and dozens of useless wooden pieces that could have been 80% less with the exact same result!
Hallelujah!

Relatively good. The assembly took almost 6 hours because it had many pieces and they had no indication on each piece, so I had to figure out what each piece was and mark it with a marker so that I could find it more easily later. The instructions were quite confusing, some images were upside down and didn't make sense. Mediocre to low quality compared to the price, many of the pre-drilled holes were crookedly made, making the assembly even more difficult.
