Others have commented that it works as expected and I'm sure they do if you can drill clean holes in your cinder block. In an older home, older than the block, you may find that the holes are not precise enough to grip and properly hold the jack. In my case, half the ones I installed gradually pulled away instead of biting as I tightened the nuts. With older blocks, sleeve anchors give better results.
