Review: Good sturdy product. Works as expected to.
Review: I used these to support a set of stairs up a slope in our back yard. I found two things that made installation easier. First I used a 7/8" x 18" spade bit to make a pilot hole. This eliminated some of the mis-alignment when driving the it into the ground. Second, as the picture shows I used the Bubble Level app on my phone to insure proper alignment. I would check it about every 4-6". These are the 6th and 7th of these I have used and have not experienced the failures others have mentioned. The others were used as bases for fence posts. IMPORTANT NOTE: the posts were secured to an existing chain link fence system. These WOULD NOT work with freestanding fence posts.

*by J***K on 2 June 2024*

When Halloween pranksters took out about 16 mailboxes in the neighborhood, I was delighted to find these aches that I could use to replant the 4 x 4 mailbox post. I did not have to re-dig a hole, fill it with concrete and insert a new post. I was able to use the old post With one of these post holders and sink it easily with a sledgehammer. It is solid and straight. I gave one of the extras to a neighbor and I am saving the other two to install some 4 x 4 posts for a car shade. They did the job easily and as promised.
