We love the course! It keeps our little one very busy. The equipment has been very durable and efficient. At no fault of this course, a slack line was needed in our case. We purchased a heavy duty slack line and all as well. It would have been nice to have one included.This obstacle course is extremely dangerous. The tension cord did not hold tension while my 40 pound 5 year old was climbing and it came crashing down. She nearly broke her wrist. look elsewhereWe got this for my 6 year old to use in the backyard. Took me a few tines to get it set up, as I didn't know the best placement for the various items. I have to set it up, and then take it down to rearrange things. However, it wasn't that bad. We don't use it as its full length as we don't have enough room. But we were able to hookup 6 attachments and that has been enough.Loosing the ratchet was a little hard and scared me the first time I did it.Some downsides:. It's very hard to get it tight. Even now, when my son uses it ( 50 lbs ) it does droop a bit. He has to keep his knees up while using it. But even with that, be absolutely loves it asks to use it a lot.Overall, very happy with it. Only wish we had more room so we could extend it some more. But even now, it's enough to tire out a hyper 6 year old.Our son absolutely loves it!!! It is sturdy and easy to hang up, the tree protectors are great too! The only complaints I have is the cargo net could have a little more weight to it. It seems to move in the wind so much that our son has a hard time climbing up it. Also it does stink that if you want to change up the course you have to take the whole thing down.We installed this above an existing slack line and it became an instant hit with the kids in the neighborhood. It has loads of accessories that can easily be moved and placed in a different order on the line in seconds. It was easy to install - but lacked directions regarding the accessories. A few tips: put the belt buckle looking loops on the line before putting it up around your tree. These are where you will attach the accessories. Move them to the distance you want on the line because once it is up, ,you will be unable to move them without loosening the tension on the ratchet. If they are spaced pretty evenly apart, it generally works well for all the attachments. Also, if you plan to use the large, black round slider ring, it needs to go on the slack line before you run it through the ratchet and attach it.I got this for my mom and I for a fun quarantine activity and we were super excited. We have two trees on our property so we figured it would all work out but in order to have the course hold up and not dip the tree diameter needs to be at least 12 inches. Our trees were not thick enough at nine feet above the ground so we had to take it down. Now we just use the slack line, which is excellent. Like many other people who reviewed this, it is very tedious to put up so once you put it up you’re going to want to keep it up. If my trees were actually thick enough to accommodate the course then this course would be excellent and I recommend it.I ordered this as a gift for my grandchildren. The package arrived, bursting at the seams. It was only in the original packaging (not inside a pouch or box for shipping) and had been tightly wrapped with shipping tape. The bottom of the box was gaping open nonetheless. I hoped for the best as it appeared that all the parts were included, but there were no instructions for assembling the parts. Being that it is the busy holiday season we do not want to risk ordering a new one and have it not arrive in time for the holidays. Hopefully my son's engineering abilities will enable him to put it together properly.We have it hooked to 1 tree and our deck post. My 9 year old is a bit big so it hangs too low. Need to hang higher than you think. Set the obstacles in place before hanging b/c it’s too hard to move once up.Les matériaux semblent de bonne qualité. Les couleurs sont vives et attirantes pour les enfants. Mon fils adore son parcours "Ninja". L'opinion des parents es mitigé. Le montage des obstacles sur la ligne de nylon est facile mais attention aux brûlures par friction quand vous les déplacez sur la ligne. Aussi, mesurer bien la distance entre les obstacles en pensant qu'une fois la ligne tendue, les obstacles seront plus éloignés les uns des autres. La fixation sur les arbres est un peu plus compliquée. Attention de tirer au maximum le surplus de la ligne de nylon AVANT de commencer à utiliser le mécanisme qui sert à créer la tension. Attention si vous devez désengager le mécanisme de tension: mon conjoint a failli y perdre un doigt! Malgré tous les efforts afin de tendre la ligne de nylon, elle s'étire considérablement. lorsque mon fils s'accroche sur un obstacle, la ligne descend énormément et ça rebondit beaucoup. Aussi, lorsqu'il lâche l'obstacle, le rebond de la ligne fait enrouler les obstacles sur la ligne. Nous devons toujours avoir un perche tout près pour dérouler les obstacles. Le nombre d'obstacles est insuffisant pour utiliser toute la ligne de nylon.It took us 4 tries to install this rope, there were absolutely no instructions and not enough requirements. It has to be installed very high to account for the stretchiness of the rope. The further you are the stretchier it is…you will need ladders…this attracts kids, many kids but it can only accommodate two at the most…the picture on the box does not match with the actual item so we had no reference on what order to put them in…it is practically impossible to do the parcours in one go but it’s fun to watch the kids try. The climbing rope is actually a hazard, would be better to use a knotted one.We are not using the zipline so cannot comment on that. We bought it to install the different ninja line components to the exposed beams in the basement. They are of very good quality. The "swing" is a trapeze for my youngest. My 6 and 3 year olds cannot get enough of this. A perfect buy for a covid winter.Awesome product, a lot of fun for the kids. I really like it.Everything about this ninja line is great in theory. I have it on two very solid trees and tightened it as much as I can. Unfortunately, regardless it hangs so low when she is on it she is almost touching the ground and can’t swing from one obstacle to another. It says hold until 250 pounds but she is all of 50 pounds so not sure why it has so much slack. It arrived quickly and was easy to install.
