I gave four stars because the plastic parts break very easily. After drilling holes in my wall and inserting the anchors, the plastic piece broke before I could attach it to the wall. I ended up having to buy another set because I had one just after it broke. I loved how well it held up! We moved into a military building and there was just a hairpin on the wall where we hung the TV. The houses are outdated and the shelves don't meet the new building codes. I installed it myself, without my husband, everything was easy except for the place where the plastic handles broke. If you don't want this, I would suggest being careful with the anchors and not putting too much pressure on them.
