“If you have two trees at least 50 ft apart in your backyard, get the kit and install the zipline. It's so much fun and my kids are enjoying outdoors every day. Building a platform can be challenging, but the zipline set up is very easy even for a beginner like me. The Hornet kit comes with a good quality trolley and a rope drafter sit allowing for an instant fun rides. Top quality products and very sturdy. The price is reasonable. I bought harnesses and other supplies separately. Also, I made a separate bungee brake system but you can buy the brake kit as well. You should definitely consider some form of a braking system. Overall the kit is highly recommended.”
