It does sag a little in the middle , but if you mount it high enough then it’s not an issue. Will be putting back up in the spring to keep training. Im 6’ 160lb for reference ### ⭐⭐⭐⭐⭐ Safe, easy to install *by S***A on September 18, 2025* Such a nice thing. My kids love it. It was very easy to install and looks safe. ### ⭐⭐⭐⭐ Loads of fun, but lasts about a year with daily use *by A***R on May 18, 2021* (1) when we ordered this originally it arrived without the hooks. We got a replacement set. From the other reviews, it seems like we were not alone in having this experience. (2) We and the kids on our block have used the ninja line daily. We've switched out the different elements (added a swing and a climbing ladder for younger kids). The kids have played with it through every season. It has been nearly a year since we ordered the ninja line, and slackline has started to wear. Given how much it is used and how much varied weather it has endured, I'm impressed with how well it has held up. I'll be ordering a replacement line! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/478548932-flybold-slackline-obstacle-course-for-kids-ninja-warrior-training-kit](https://www.desertcart.co.uk/products/478548932-flybold-slackline-obstacle-course-for-kids-ninja-warrior-training-kit) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-21*
