No 1 Lounge T3

Has anyone had any experience of using the No 1 Lounge in T3. Have read lots of reviews with both good and bad comments.
Looking to arrive around 5pm on a Thursday evening early March. Wondering whether that would be busy due to "rush hour" or not.
Booking direct with Virgin is the cheapest option out there.
Just wondering whether or not its worth it ??
