I have mixed feelings about the two trays I bought.  The reason I bought the tables were to make it easier for my elderly mother to move the tray - and the wheels have assisted in that.  After I assembled them (very easy to do) - I really liked the way they "looked" - the thing I did not like is that you can not put very much on the tray unless it sit over the area where the leg - the further you get away from the leg - the tray starts to bend downwards - I am not talking anything heavy (just resting your arm on that area causes the tray to move downwards) over a short period of time - this will cause the tray to become lose and or snap free.  I fixed this by adding another table leg.  I bought a leg flange, table leg, and wood stain.  It turned out very nice - but for what I paid for these trays - I should not have had to make any corrections.
