I've used them in the past and they're great. However, I strongly recommend not using thicker screws than those included in this kit. If the screw is too thick, it will begin to drive the anchor deeper into the wall. If the anchor penetrates even a half inch into the wall (depending on the thickness of the drywall) and isn't flush with the wall, it can simply poke a decent hole in the wall instead of an anchor. Luckily the fairly clean holes in my wall were perfect for some of the latches I had lying around and I used them instead (also a highly recommended product). I said I've used them in the past and they're really good (if you use them right). Also very easy to use.
