FofanaKids Ninja Slider Slackline Zipline Pulley - Red Stainless Steel Pulley Slider - Transforms Slackline into Zip String & Obstacle Course - Quick 2-Min Setup for Backyard Zipline Kits

Update- the seller sent another pulley which is way better quality. No issues whatsoever. Kids love it. Great customer serviceInstalled the slack line which wasnt too difficult but did take a little time and a ladder. The quality of the line seems fair - noticed fraying on a side seam that would need to be monitored for safety. The bearings on the pulley were not lined up perfectly and did not spin well straight out of the box yet appeared to be new in packaging. I have one child that weighs 70 lbs. The bearings on the pulley broke after one use. Will be returning it. Don't waste your time on this one. I should have paid more attention to the reviews

I recently installed the Ninja Slider Zip Lines for Kids and Adults at my kids' gym, and it has been a huge hit with both the kids and the adults!Pros:Fun for All Ages: The zip lines are designed to be enjoyed by both kids and adults, making them a versatile addition to the gym. The excitement of zip-lining is something everyone can appreciate, and it’s become a favorite activity for all age groups.Durable Construction: The zip lines are built with high-quality, durable materials that can withstand a lot of use. The cables are strong and reliable, ensuring safety and longevity even with frequent use.Easy Installation: Setting up the zip lines was straightforward and didn’t require any specialized tools. The instructions were clear, and it was easy to get everything in place quickly.Engaging Activity: The zip lines offer a thrilling and engaging experience that encourages physical activity and helps develop coordination and balance. It’s a great way to get kids moving and having fun.Adjustable Length: The zip lines come with adjustable components, allowing you to customize the length to suit different heights and skill levels. This flexibility ensures that everyone can enjoy the activity safely.Cons:Space Requirements: The zip lines require a significant amount of space for installation. If your gym area is limited, you’ll need to ensure that there’s enough room to accommodate the setup without crowding other activities.Weather Dependence: While the zip lines are designed for outdoor use, their performance and longevity can be affected by harsh weather conditions. Regular maintenance and checks are necessary to ensure they remain in good condition.Overall, the Ninja Slider Zip Lines have been a fantastic addition to my kids' gym. They provide a fun, engaging, and safe activity that everyone enjoys. Despite the need for ample space and some weather considerations, the zip lines have proven to be a worthwhile investment that adds excitement and value to the gym experience.

This zip line was simple to set up and worked great for one day. The second day, two of the bearings failed and the trolley stopped moving along the strap. I see many customers have reported the same thing so this is an inherent flaw in the product. The bearings are cheap and will seize up after a few uses making the product unusable. Poor quality

Update at bottom:I followed all the steps, did all the math, load tested. My kids used it for a week and the slider pulley ripped itself apart. 1 kid at a time, supervised, no more than half the rated weight at any given time. So far seller has not responded. Please make this right and send me a new slider pulley!Update: they sent me the new part a week later.

keeps the kids happy for hours and so easy to install and take down! well worth it!

Worked great on our ninja line-it was the first challenge and the kids loved zipping down to the next challenge in the line! It weathered well too so was very durable.

Update: we did receive our money back even without us requesting it. So I am thankful to the customers service!It was fun while it lasted. It only lasted a week. Half the ballbearings broke after a week use, there is no way to change them so the whole slack line we also bought from Ninja fofana became useless. Very-very disappointed with the quality. Just a disclaimer - the slack line was used by two kids - both weighting less than 110 pounds, so definitely far from the weight limit. They were so happy with a home zip line and such a blow. No, don’t recommend!

Worked great while it lasted. Then broke after only a short time of use.
