Shipped really fast and simple enough to install. Kids and Adults love it - appears to be high quality and loads of fun. ** Pro Tip ** Followed the instruction provided for majority of install, but used a come-along and my truck to tighten the line. Pulled to line as tight as I could by hand to get it up off the ground, used one of the cable clamps to make a loop near the end of the line, attached the loop to the come-along, attached the come-along to my truck that was positioned under the line, tightened the line with the come-along and attached 2 cable clamps to the tightened line around the tree, took the 3rd cable clamp off the loop and attached to the tree area and wallah - one person install of zip line!
