In reality, the quantity depends on the depth of the hole and the difference size between the post and the hole, not the size of the post.

The stuff does look fun, but is way too expensive for me.

I've used this product to put up a flag pole. At 75 years old, it was a lot easier than using cement with the weight and mixing required.

I like the weight concrete adds towards holding it down.

And sure, it has to be a LOT cheaper to beat a bag of post hole quality ready mix
