I am a grandfather who purchased this 6 years ago for his grandchildren. They had hours of fun on it and so did all the adults. All equipment is in excellent condition. It is not a cheap backyard system. It is a super strong steel cable with upper level components bought from ziplinegear.com in Washington state. Included with the zipline are multiple harnesses for small to large users plus a tether line to attach for small children (you can walk behind them and manage the speed). Original cost was $1,000 plus extra accessories. "The Rogue Pro Zipline kit at ziplinegear.com" We can arrange a meetup for inspection Leander or Cedar Park also.
