This system best met my needs because it was most flexible in shelving positioning. I have VHS, DVD, CD, and oversized VHS.
The shelves can be inserted in so many ways to accomodate various sizes of media. Also, a lot of wall space is utilized with these fairly high units. I actually modified one of the four I bought to be a two vertical row unit instead of three rows. This was easy and allowed me to maximize wall space usage while not covering up my floor heating vents. Construction material is OK, not primo. Some of the locking nuts fall apart if tightened too much so be careful tightening the locking nut into the auger bolt. Same locking nuts as in most build it yourself furniture.
