## Customer Reviews

### ⭐⭐⭐⭐⭐ Slightly better than "Good Enough"
*by M***T on September 19, 2025*

Overall I would say these are solid bases. If I have a complaint, it would definitely be that the Philips head on the lag screws did not hold up well when driving several of the screws in. However, I didn't feel that issue was a dealbreaker because the ones that did strip were able to be fully seated with a socket. Just took a little longer when that happened. When compared with prices at big box stores for similar products, the value is certainly there. Plus, with Prime, they arrived next day which kept our job moving.

### ⭐⭐⭐⭐⭐ Includes everything you need
*by D***R on September 21, 2025*

These work great! They include the expansion bolts too. Be warned if this is your first time. You will need most of the other stuff shown in this picture for concrete. SDS Type Rotary hammer is a must. Also it takes an sds drill bit 5/16. When it says to hit the expansion bolts in instructions, just lightly tap them in, they tighten once you use wrench(expansion). Hope this helps

### ⭐⭐⭐⭐⭐ Awesome product for any 4x4 project
*by B***Y on August 27, 2025*

These are amazing!! I bought the four pack and used them on the 4x4's to make my fire pit area. Great quality, very sturdy. Would definitely recommend using these when building a deck or fire pit area as I did. I looked at Home Depot and Lowe for a similar item and they were $25 each. These are a great bargain, but not bargain quality.
