Bought this as an alternative to digging post holes to extend our garden fence. While it worked, it was nearly impossible to keep this square as you are pounding into the ground. We are going to keep it in for this growing season, but will pull it out and use concrete next spring.

Rated 4.0 out of 5.0 by homeooooner Worked for me but.....
These worked for what I wanted to do but let's see how long they last below ground. Also this product certainly does feel lighter than previous versions. It helps to cut a section of post, 8" and install it securely then pound down on the section of post. This helps from destroying the product.

Rated 1.0 out of 5.0 by spinkbob Avoid These. Imported junk!
Installed a 6' stockade fence using Stanley (tool manufacturer) spikes twenty years ago. Stanley doesn't make them anymore, too bad. Twenty year old Stanley spikes withstood Hurricane Sandy. Recently replaced three spikes in my fence with this brand. Not one lasted 6 months and all broke in moderate winds. Each spike broke away from the post collar. Weak material and/or crummy welds? Maybe you can use these for a mailbox but not a fence!

Rated 1.0 out of 5.0 by Jake Worthless - Save Yourself a Headache and Use Concrete
These are much easier to install than digging post holes and using concrete, but if you are building a fence that you want to stand up any amount of wind then use concrete. Also, they rust very quickly.
I purchased 9 of these anchors to build two fences. I used 4 anchors for one fence and sunk the 5 anchors for the second fence. Before I could put up the second fence a wind storm came trough and blew over the first fence. Three of the four anchors broke clean off at the joint and one was severely bent. Not wanting to face the same problem with the second fence, I dug up all 9 anchors and tried to return them to Home Depot. Home Depot would not take the three broken anchors or the bent one, and of the other five that had just been in the ground (without a fence), three were too rusted for them to take back. Too rusted? I've had them for three weeks?
I am seriously disappointed with this product. I read several reviews for Oz-Post and was very impressed with the technology. I asked a store associate for Oz-Post and they recommended this product. From what I have seen, the quality of this anchor is nowhere near that of Oz-Post. These anchors have poor welds and poor corrosion resistance coating. I would definitely NOT recommend this product.

I installed these  anchores last fall ,2014 for a 6' fence [4 panels]. 2 rusted and broke at base less than 6 months after install.Whole fence less than 100 lbs.Didn't work waste of time.Replaced with concrete and 4x4 like I should have to started with like everyone says.These MIGHT work for a mailbox post but thats it.

Rated 1.0 out of 5.0 by GT Lots of work to use!
These items say they are for 4 x 4 posts. A 4 x 4 post doesnt fit in these with out shaving off the sides and edges to get them started and then they open enough for your post to fit into but then the provided bolts are too short and you have to get longer ones. I am very disappointed in these and if I didn't have the right tools and not have wanted to travel back to my store I would have returned them. I am not real happy with my project and will eventually replace my posts by digging holes and pouring concrete for my posts. The extra labor of digging a hole and the much cheaper cost of concrete is a better way to go for my money!

Rated 3.0 out of 5.0 by JoshMc Good post holder, cheap bolts
I bought two of these post holders, one for a mailbox and one to support a gate. The post holders are very sturdy. I put them through fairly rocky ground and had to "restart" a couple of time to find a spot, but didn't see any deformation of the posts.
Two things could be improved: First, they do not hold a 4x4 as tightly as they should, I had to shim my post to remove the play. Second, the bolts that are shipped are easily stripped. You need to use a fair amount of torque to get a good grip on the post, and even a properly threaded nut caused stripping on one of the bolts.

Rated 5.0 out of 5.0 by JosiesDad Easy does it
What a pleasure using the groundmaster post system.It made my building experience an easy task.I was really fearful of doing this project due to the fear of the unknown.But,Once I got started it went right in. I do recommend checking and rechecking your measurements cause once you are in with your groundmaster post ,you are in! A nice size sledge hammer makes the job instant gratification.
It is currently holding up my privacy lattice wall and is supporting it nicely,and we had some windy days. I would recommend this to anyone who is doing a fence or privacy wall project.
