Review: Worked fine and more affordable than Home Depot or Lowes! - I don't have the infrastructure or need to test the actual strength of these anchors, but they seem identical to my Home Depot-sourced other ones, and were substantially cheaper. They dropped into holes in concrete just fine and took a set, letting me mount a hose spool, just like I needed, so there's not much else to say beyond they were functionally fine. I'm not going to use them to install a vehicle lift or life-saving equipment, but then again I'd let someone with an insurance policy do that, so if something goes wrong my widow would have some recourse. Installation is typical of drop in anchors; one needs a hammer drill and masonry bit but it's straightforward.
Review: Good product, easy to use. - These work very well in concrete and stucco. They are a great value. If you were to buy they at the big box stores, you would pay three times the price. I use these for all kinds of projects. My latest use was to mount a retractable hose reel to my house. You do need masonry drill bits to drill the holes to put these into. Also, it would be nice to have a hammer drill to speed up the process.

### ⭐⭐⭐⭐⭐ Good value: installed an outside gate
*by F***E on August 17, 2024*

Good quality as I used this to install an outside gate (it's a cheap plastic gate so I wanted to keep the option of changing it out in the future so this allows me to unscrew the bolt without drilling more holes later). You'll need to buy a drop-in anchor tool to get it to work properly; it will likely break or not work if you use a nail and screw to hammer it. This does not have a "lip" to catch the edge of your hole, so you will need to be careful how deep you drill your hole through masonry (some of the more costly versions has a lip).
