🔧 Ninjaline Wheel by Slackers SLA803 Review

I was building a zip line for my kids and came across this product while browsing Revain. I honestly don't quite understand why, but kids love it and prefer it to anything else they've used before. I don't think you can argue with success.

Easy to add to our Ninja class after my 80 lb daughter blew it away the second time around. This was the first day of installation. Luckily it landed on her butt and not her back or neck. Light bruising. Very low quality in terms of security!

The wheel is very well made. It's sturdy, the bearing works well and the fasteners are perfect. No complaints. I installed it in my kids basement and they love it. All of the gear I've ordered from Slackers has been top notch. I ordered several items from other manufacturers and sent them all back.

It's just another hold, but it sinks 10 inches when you grab it with your first hand. He turns and doesn't turn. Holding to one side will take you 10 inches down and touching the bottom if you didn't set the main line height correctly. Regardless of your comfortable/safe height for attaching the main user lanyard, you may need to add 10 inches to overcome this obstacle. All obstacles end up higher when this is used.

From my 7 year old: "If you want to build a ninja warrior course, you should get this one. It's really hard to get through because if you hold on to it, it flips over and makes you dizzy and makes you want to fall. And that's actually a good thing, because it makes the course that much more difficult, and Ninja Warrior courses are supposed to be difficult. And it is also very difficult to turn on it to the other side, because when turning, it only turns, so it is more difficult to get to the…

please do not buy! I bought it for my 10 year old daughter who is very slim and athletic. Today she was on her ninja set that includes a wheel. The plastic in the leash broke and she fell to the ground and the big round metal hit her in the head! I am so upset as this could have resulted in serious injury! I will write a separate report on this to customer service. This is a very dangerous toy! Do not buy! See attached photo!

This is a great addition to our Ninja slackline. Children love to hang onto it and let it spin properly by turning their body. The bearings run very smoothly and look good. Parents even like it to stretch their backs. The only thing to watch out for is when someone jumps off it usually swings heavily and depending on how low your slackline is this can mean swinging back and banging your head hard on the user or someone nearby to hit (e.g., an observer). It's heavy and has some power behind it.

The Ninja Spinner itself is a great product with a solid construction and no sharp edges. I think there should be a better description of the subject, stating that for this to work properly and safely the spinner must be attached to a safety swivel, otherwise the connecting cable will just twist and then cause rotational torsion. A ninja line that the entire assembly is attached to, which can result in a catastrophic failure, fall, and injury. The ninja spinner should contain relevant…

Well done! This is an excellent product. I like to climb high to the top of the forest and work on my breathing and rotation. I've been doing this practice for many years, just with a string. I climb high on a tree, hanging by my hands, and starting from a branch I twist and hold, inhale, and the higher you climb, the more you cling to the suspension. The great thing about this tool is that I can hook it in with my feet and do it upside down. Outstanding product, thank you for posting it…
