You can't count on the flatness of this the way you count on a real fixture table or a milling machine table, but it's perfectly fine as a work table, and I have bolted plenty of things to it. It's light enough to move around easily, but it's sturdy enough that I have a 100lb anvil and a torn apart 60 lb vise on it, and I can slide it around without the legs racking all crazy or anything. I don't regret the purchase.
