Review on Ultimate Obstacle Slackline Equipment: Unleash Your Playground Training Experience by Chad Black

I gave this product 1 star due to recent safety issues. I bought Ninja Slackline on Black Friday as a Christmas present for my kids. I installed Ninja Slackline according to the instructions in the package. Installation was easy and even easier to handle if you have a helper. The contents of the box were well packaged and everything appeared to be of good quality. After the slackline was set up and the accessories in place, I checked the lanyard that said "440lb weight limit." old to start playing. About 20 minutes into the game my 8 year old daughter began to wobble and the metal buckle snapped causing her to fall to the ground and get hit by the buckle. Maybe it's an accident; However, I cannot risk letting my children play on Nijs field until I have spoken to the company. Since it's Christmas I have to move on on the 26th and will leave an update with the solution! Update after speaking with the company, they have supplied new buckles which are designed with no welds, no problems since. The company still gets 1 star because there was a quality control issue. If you buy a set make sure the buckles are not welded as shown in my photos!
