And flimsy as hell. I don't even trust setting a full beer on those tables, but for $8, they're cheaper than a set of beer coasters.
I put a 50" plasma tv on one for a few days before I could get around to getting a better stand. Now it serves as a cheap coffee table and has been loaded to capacity with beer bottles several times.
I think they're surprisingly robust for an $8 piece of new furniture.
