I have a similar table (mine just has one leg that swings out from underneath) from Joanns and really like it. It has several delicate parts. On mine the plastic clamp for the metal part when the leaf is extended is screwed into the particle board, and pulls out easily. Also the roller feet have plastic inserted into the metal legs, and one of these snapped off, so it does have its vulnerable parts. I have seen similar tables that have storage shelves underneath the middle part, that look more sturdy.
Having said that, the convenience of such a large surface is well worth the price, especially the sale price you quoted, and the fold up feature for storage is great.
I'm 5ft 5 in and the height is perfect for me.
I love mine.
