Just like most others have said, the shelves are poorly designed and there’s a gap between. The unit was very wobbly and I have a thick trim at the bottom of my wall that makes it not possible to drill it to the wall. I was able to hold the unit level as I lowered a shelf on top of it that I could secure to the wall and have adhesive tape to stabilize the unit with it. If I could’ve found a better quality unit that had similar dimensions I could buy that one.
