Review on Space-Saving Wall Mounted Wine Racks - Organize and Display 6 Red Wine Bottles with Ease! by Samantha Ballard

Love how simple they are! Four screws are required, which are included in the scope of delivery! Even a bubble level is included to make sure it's straight. My only advice would be to make sure my bottle is level, but what I didn't take into account is that the right side slopes a little more than the neck of the bottle, so you can see in the picture that they are tilted a bit. Looks good but I had to wear a tie around my neck to keep the bottles from slipping out.
