I bought this as a temporary work desk at the beginning of the madness in March 2020 & to be fair its done ok, its stable/sturdy & an office chair slots under it fine.
I have 2 monitors on a stand, a 6.5kg cat occasionally, a laptop, keyboard, mouse etc and its big enough - there's not really enough room for paperwork or notes though.
The surface is good though it does mark but can be cleaned. One weird thing is the top seems to be made of an injection moulded foam/plastic and this has sagged ever so slightly around the hard fixing points underneath - it means the top has a few dips & hollows in it. They're not bad & you probably wouldn't notice if used as an outdoor/occasional table.
For £30 it was a bargain and has served well during lock-down & working from home, I bought this thinking short-term and 2nd use as I never expected I'd still be using it 9 months later & probably longer still. Ideally to use as an office desk it would be better if it were 1200-1300mm wide.
Once this is all over it will become a fold out for the garden etc (it does fold well to approx 100mm thick)
02 Feb 2022 update. I'm still using this foldout as my workdesk nearly 2 years on from the start of the pandemic & whatever anyone else says its still rock solid, has two monitors on a desktop stand, a laptop, mouse & keyboard - and quite often the cat will camp on it while I'm working.
I'm 6'2" & have not problems with space, I'm using a decent office chair too.
Occasionally we've used this outside and it folds/assembles no issue. Quality is also fine
