Great idea for most campgrounds, as they screw into the dirt and go deep. Putting one at each corner should help to keep that tent from becoming a kite. The only weakness is the rock-soil that we have here in the rocky mountain area. Half the campgrounds don't remove this rock from the soil, so penetration can be a struggle. Just gotta try different angles to see what might work.

So I give em 4 stars for being a good idea that works for some situations, but not so well in others.

Solid rebar U-stakes. I am going to use them to stake down the bottom of a chain link fence to keep my dog from squirming underneath. These are coated to reduce the risk of rust and sharpened to be able to poke through the ground easily. They should do the job for trampolines and other things as well.
