Great product - we bought two so the kids could walk along the top of one and use the 2nd to hang from. Recommend stringing over 24 ft as the spacing was just right for the obstacles and hanging ropes etc. product seems well made, would purchase again

This product was recommended to us by bradlywest.com and what a great recommendation it was/is. There are only a few things that can compete with Fortnite (i.e. your children sitting on the couch for hours). This "Ninja Warrior" Intro kit is one of those things that will make your kids love getting off the couch and playing for hours outside. Not only is it really challenging, but you can adjust the obstacles on the slack-line for beginners or intermediates. Take off the obstacles and it becomes a really sturdy slack-line for balancing. Very high quality product. Every stitch on the line and each metal joint and piece is very durable, built to last thousands of takedowns and reinstalls (which can be done in 10 minutes or less!). Very very satisfied with the purchase.

It is easy to install, but it sags a little depending on the kid's size. Our younger ones can play on it fine, but our 14 year old doesn't enjoy it as much since it gives under his weight. I'd say 70ish pounds and down will find it fun to use. After that, it gets a little iffy.

My kids love this! 8 year old boy and 7 year old girl. There are 2 extra pieces shown here that do NOT come w the line. I bought the rope climber and spinner shown to the left after we put up the ninja line and needed something that my daughter could reach better. I love that this blends in so great to a yard with out standing out like a sore thumb like large jungle gyms. And costs so much less!!! Advice. Layout all piece where you think you want them and attach BEFORE you tighten line. Also a good idea to get extra clips and put them on all loops so you can easily move items around after tightened.

Kids like the line. It's nice that objects are easy to swap position, but works best with slack in line. Seems durable and has entertained kids (10,9) for a few hours. Durability has yet to be an issue, though I would recommend taking it down when not in use. As with all things left out, it will become fragile with sun and dirt exposure.

Our daughter is in love with American Ninja Warrior and loves “training” in the backyard. This product has a great find and was very easy to set up. I do recommend hanging this product a little high because you need a few extra feet to hang. It’s a great quality product and I’m very happy to see my daughter playing outside again.

We purchased this ninjaline for our daughters, 3 and 6, to make our backyard more fun during quarantining. They LOVE it! It was very easy to assemble and is of good quality! We bought extra accessories to be able to change it, unlike a swing set!

The media could not be loaded. With a busy family that includes my nine year old daughter and four grandchildren I need to keep the kids busy especially during the holidays. Grandmas house equals fun all day long. Very happy with the Slackers Ninjaline kit. Can’t wait to surprise them with the zipline for Christmas!
