My unit arrived without instructions, I thought it was self explanatory but it very much wasn't, and in the process of setting up, I damaged bits of the wood. It was only when i searched online i found a manual. Unfortunately you also need a drill to assemble this! which for a student living in a student house, was not to hand. I didn't realise i was buying a DIY project.
To prevent future problems i think Thomann should provide instructions and say on the website that one needs a drill. I regret buying it in white, as it looks rather garish and office like. I also wished the rack was less deep, as no outboard is that deep, it does take a lot of space. It has been up for 2 weeks and hasn't collapsed yet which is good, but I am making this information known to you.
