A couple of quirks, but otherwise a beautifully built desk.
I had a minor issue with the assembly of the main desk with one of the screws accidentally going into the wrong place, which I did not realise until afterwards. I decided to leave it in place because it would have been a total pain to fix. While this wasn't a deal-breaker it could have been avoided if the pictures on the instruction sheet had been clearer and/or the screws marked better to distinguish each type more clearly.
The keyboard trolley is also a tad flawed in design. First, it is awkward to take out from underneath as it is super wide, being designed for 88-key keyboards, which is admittedly what I have, but it constantly gets stuck running into either one of the legs so it's almost like the table design did not originally accommodate the keyboard trolley. Secondly, it would have been better if the height-adjust feature was a slide mechanism instead of a screw one. Because of this I've got it in one setting where it's a bit too low, but the next setting would be too high. I've got a Roland A-88 Mk II which is a standard size 88-key keyboard, albeit slightly wider than most, so this height issue seems like a consequence of not enough thought being put into the practicality of it. The solution would be of course to take it out from under the desk, but that's the whole reason I bought it, to put the whole thing under the desk as shown in the pictures! Lastly, the wheels on the front of the trolley could have been rotating ones, like those you see on shopping trolleys. This would have made it a lot easier to move around. But as it is the trolley is not easy to move around. Not a complete deal-breaker but I may have thought twice about getting the trolley had I known it was going to be like this.
But beyond all this, the main desk is an amazing desk. It is very sturdy and the overall build quality is top notch. I got the wood finish which is aesthetically pleasing. All my friends who have seen it want to get one too, and a couple of them don't even make any music. It is my best music-related purchase to date, and without a doubt the best desk I have ever purchased period.
Side-note: I got the optional cable management tray but I can't see how it is going to do too much to help my particular situation so it's sitting in a corner unattached.

Spacious, material is quality and most importantly can fit my 88 keys piano under the desk. Wouldn't change a thing about it
