Review on 🏗️ Fast 2K Fence Post Mix: Advanced Composite Footing Compound for Effortless Fence and Mail Box Post Installation! 2.2 lb Bag of Revolutionary Concrete Alternative. by Adam Abner

I have been in the construction industry for almost 20 years and love trying new/innovative products. I am giving this 2 stars because the manufacturer has WAY overestimated the performance of their product when technically the product actually works. I used this to put my personal mailbox (nothing notable about the placement) which is 4 x 8 (reusing an existing post) in a 9" diameter x 24" deep hole. The product table says "1 bag required" for a 6x6 rack hole that is 10" diameter and 36" deep. Bore 9" x 24" = 1526 cu. 2K" = 758 cu.in. Manufacturer specs = 2826 cu.in. 6x6x36 rod = 1296 cu.in. Delta = 1530 cu.in. 1 bag but I actually needed 2 or 3 bags to install it properly eh a pole they made in their video plus some for less than half the price.
