Good design

Seems to be well built. I like the design so that bottom of posts are elevated and no chance of being exposed to standing moisture for extended period of time. Like the fact that they provided necessary hardware (I only used 4 of the expansion bolts per post, not six). Directions are adequate and at least they tell you what size drill bit to use. Only using them to support some short 4x4 posts.

Highest Quality Craftsmanship

I did not use these for their normal purpose. I was building a simple, but heavy, mobile workbench and wanted to connect 4x4 legs to solid slab top. These worked perfectly. They are extremely well built and the manufacturer was extremely generous with the hardware included.

Good quality

Good quality. I would definitely give this product 5 stars, however, I had to shave some wood off my 4x4 posts to get them to slide in. Could be my pressure treated wood was extremely wet.

Exceeded Expectation

The post bases were exactly as promised. They look great, are heavier duty than I expected, and came with all of the necessary hardware, including a wrench. These will work great for the foundation of my corner posts for a new outdoor living area.

Great value! Has all you need to attach.

Out of pure procrastination, I don't usually leave reviews, but with this product, I just had to do it! I'd give more stars if I could. Usually when I have a project like this I spend too much time at Lowe's or Home Depot looking for the attaching bracket and then all of the hardware to go with it, while also hoping I bought the right sizes, and don't have to run back out. This came with pretty much everything I needed for probably cheaper than I could have bought it for at the big box hardware store. Brackets are well built, sturdy, and all the hardware is included... Whether or not you're attaching to wood or concrete. Once I had these on hand it was a quick install. Great job to the seller. I would definitely buy these again! My only complaint is I could only buy them by fours. I only need three but it was still cheaper to do it this way then do it locally. Plus, again, it had everything I need.
