I like my chairs. 
The chairs were fairly easy to assemble. Be careful to place them correctly before tightening so you wont have to take them off and put them on the correct way.
The only small critique is that the hook on the back of the chairs bang a little when you pull the chair to sit as if it cracked, when its not. Other than that, they are very comfortable and easy to maneuver when pulling out and pushing in at a table. Its been a couple of months and there are no signs of scratches on the metal legs with light use of them.
