Not 100% great for looser soil
"As the title suggests, these anchors are heavy duty but not the most useful for soil that is considered loose and dry. You wanna make sure your soil is more tightly packed than mine. In my case I’ll have to probably concrete those things in for extra stability but 4 stars given because despite this, they still add a great layer of support and stability. Perhaps the flared skirt part could be wider, that’d be more effective. Other than that, and if you have standard soil, you’ll be well off with these bad boys. Highly recommended"
