I remove the keyboard tray as I found it got in the way, personally, but other than that, this is genuinely a surprisingly good desk, especially for the money.
I was initially skeptical, but after having the same standard office desk for 17 years, I decided to change. My budget wasn't huge and this seemed to be what I was after. Easy to build, no troubles with it. It does wobble a liiiitle bit if you knock it, but not major problems. Only thing I wish it did is have notches for the monitor speaker stands to ensure you're at the same angle for both monitors. I'm sure that's something I could probably modify and add myself down the line.
For those in the UK buying, shipping wasn't too bad, albeit because of the size, there's no tracking. Thomann were great in what they could provide me regarding info, but the shipping company were dreadful. The guy left me on my own with the giant desk in the middle of the street, turned up 2 hours earlier than the email said he would, and didn't send an alert prior to arriving as I was told would be the case.
tl;dr the product is great, especially within its price range, but if the UK just be aware that the delivery service may be a little dog!
