I live in North Dakota and we must protect our trees here so no screwing and drilling.I first got the strap on steps the individual ones.They were a mess to untangle.The Lone Wolf strap on ladder steps are definetly the way to go. They are worth the money. They are light and work great. I sold all the individual tree steps, on e-bay,except 2 that I use only at the bottom of a tree to get higher than the 3 ladder steps will allow, that come with the Lone Wolf ladder kit.
