I'm selling this because I no longer have the opportunity to use it. I've only used it a few times in my backyard. I played on it barefoot, so there's no mud or dirt. However, there is some staining on the belt, mainly on the sides. There is also a little rust on the lever. Please check the pictures. It's a ratchet type (see image 3), so you can easily tighten it by moving the lever back and forth. It won't loosen unless you release the lever, so you can play safely. Also, it's a long lever type, so you can easily tighten it with little force, making it easy for women to set up. About the tree wear (see image 4): This is a cover to protect the trees when attaching the slackline to them.
