As West Ham played their first game at the London Stadium, against NK Domzale, fans gave their first impressions of their new home at the heart of the Olympic Park.
And fans also shared their views (literally) on Twitter.
As people settled into their new seats in the impressive London Stadium, in Stratford, some people definitely seemed happy with the set-up.
And they didn't seem to mind that the pitch appeared to be quite far away from the stands.
But some people? Yeah, they were perhaps not quite so sure.
FYI, West Ham beat NK Domzale 3-0 - it was the second leg of their Europa League third qualifying round tie. They won 4-2 on aggregate, and advanced to the play-off round.
