Rated 4.0 out of 5.0 by Horse These worked well for my application
After removing the old post residue from the concrete anchors I was able to insert the Oz Post, seat it using a piece of 4X4 and a 12 pound sledge hammer. Then I filled the remaining void in the socket around the Oz Post with concrete. This was an excellent time saver that was easy to install and which has resulted in a sturdy new fence.

The posts went into the ground very easily but that had a lot more to do with the ground itself. My contractor decided not to rent a jack hammer and pounded them into the ground manually. You will need the OZ spacer wheterh you use manual labor or the jack hammer. They will be used father up on a hillside where the ground is drier. They do not go all the way into the ground, you will have about 4-5 inches above ground that is the galvanized post holder. If you're looking for zero ground clearance, you need to go old school and dig a hole, pour in concrete and set your post that way.

Rated 3.0 out of 5.0 by dynamite NOT EASY
The oz post anchors are impossible to get in straight. And then when they are straight they have moved an inch off the mark. It you are using these for rolls of fencing where the distance between posts doesn't matter then I think they will work great.

Rated 4.0 out of 5.0 by RedmondGardener They work well, but a few drawbacks
We're building a fence around our veggie garden, and didn't want to use the traditional pressure-treated posts near the veggies. So, we're using cedar posts I got at a discount. Problem is, cedar will eventually rot in the ground, so the Oz-posts seemed like a nice way to keep the posts out of the ground and hopefully make them last a lot longer.
The Oz-posts are definitely easy to install. I just pounded them in with a normal sledgehammer and a a short piece of pressure-treated 4x4. I encountered a few drawbacks that you may want to consider:
1. They don't hold as well as I would like in soft soil. With a few of them, I ended up setting a bit of concrete around the base to make them more solid. If you pound them such that the square top part is about halfway underground, they hold better, but I didn't do that for all of mine since the ground is a bit higher on one side. I suspect the longer 34" Oz-posts would work a lot better in these situations - these ones are only 24" long.
2. It can be tricky to get them aligned just where you want, since they sometimes shift a bit if they encounter a rock underground. This can also make it harder to keep them plumb going in, but generally that is not an issue if you align them after each hit with the hammer.
3. This is both a pro and a con - you can install them without digging a big hole like with a traditional post hole. However, this also means that if you have potential obstructions underground, you won't know it. The Oz-post will either refuse to go in, or you'll punch through the obstruction, perhaps damaging it. In my case, I hit a 2" PVC septic line and punched a hole in it. Of course, you should always use call before you dig (411), but in my case this didn't help since they don't mark the septic lines, or water lines on our property. So, before hammering them in you might want to think about what could be underground. Once I hit the obstruction, I had to dig a big hole to fix the pipe anyway, which meant I could no longer use the Oz-post in the resulting soft soil.
Overall the Oz-posts are a great product. Not any cheaper than using typical concrete and gravel, but they are simple to install, and I like the idea that I can easily pull them up in the future if I need to change something. And, I am hopeful they will extend the life of my posts significantly since there is no soil contact. They are certainly strongly built, and buying a case they are much cheaper than the flimsy post brackets that are sold in-store.

Rated 5.0 out of 5.0 Love these posts
I had to build a fence out in the woods behind my house. My post hole digger went down 6 inches before hitting solid rock. We called out a fence guy and he said he'd charge us $100 a hole JUST TO DIG the post holes. I finally found OZ POSTS and it's a life saver. However, please note that for hard rock, YOU WILL NEED A jackhammer, I couldn't budge it an inch with a sledgehammer. Also note that means you'll need power, so if it's in the way-back, you may need a generator. Plan accordingly.

Rated 4.0 out of 5.0 by Junebug Good Solution that doesn't involve concrete
These anchors are a lot more beefy than I would have imagined. I got the 24" length for a small simple shed. They drove into dry, miserable compacted dirt fairly easily using a sledgehammer and 4x4, tho the 4x4 shattered when driving the third post. No worries, just have a few extra feet of 4x4 around. If you're driving more than a few of these anchors, maybe go big and opt for the other driving methods. One thing I did have some issue with was keeping the anchor square. It may look "good enough", but take care to get them square. Trust me on this!

This is a fantastic product. We live in extremely rocky country, and I wanted an easier way to set posts than using a pick and concrete. We are putting in a deer fence. In short order we had eight posts set and they are very sturdy. We hired a strong young man to swing the sledge hammer, which I heartily recommend. The only problem we had was that the scrap lumber we put into the head to drive the post kept splitting apart.

Rated 5.0 out of 5.0 by Teamhaney Real time saver, just as good as concrete anchors
Used these to put up posts for a 4' shadow box fence. Much quicker and cheaper in long run than digging post holes and anchoring with concrete. I used a sledge and 2" black pipe with a cap to drive them. Make sure to cut wood shims to hold the pipe plumb. 4x4 lumber shattered too quickly. Fence is up and steady.
