We are not totally happy with thus product. We should have had 3 x number 2 and 3 x number 3 but we had 4 x number 3 and 2 x number 2 which ment that we had the screws showing on the inside for one of the side pieces. We used the screw covers he try and hide these but then had to find some to cover the screws holding the unit to the wall. Also the side pieces didn't fit completely flat against the shelf so there is a slight gap. This wasn't worth the money I'm afraid
