Got some some stakes in the mail today, I ordered them off Ebay from China $7 including postage for 10.
They are 7 inches and described as a aluminum alloy. They are gold colour which I don't mind as they will stand out and I will be less likely to leave them in the ground
They seem pretty much the same as the MSR groundhogs but the groundhogs are at least $2.50 each for me to purchase locally.
The stakes do not have a rope tie attached to them.
I am going on a family car camping trip in two days and will be sleeping hammock style and will let you know how they performed
