Held up well. We ran over it with our mower on accident and it still held up. Would recommend.Works for my rambunctious 120 pound pointer/lab mixused a a dog run for my toy fox terrierUsed cable with Govee String LEDs. Practical, strong, cable and easy to install.I have had this right at a month and it's a mess. The outer part has come undone in a few places causing the bare cable to twist up. It tangles up too easy. I'm already going to have to get another.Very durable and does not kink or raval like the thinner ones. Probably not good for small dogs do to the fact it's a heavier gage.I've only had mine (bought 2) since 10-23-21 (today is 11-7-31).Terrible for large dogs. It's light enough and might last with a smaller dog. Not sure about the other reviews that says they don't tangle...mine gets twisted if my dog is out for 10 min or all afternoon. Part of the problem is it doesn't swivel at the carabineer you hook to the dogs collar. So it obviously gets all twisted up.I'm already ordering new ones ?Don't waste your time or money purchasing this product. after just 3 days of use the black covering on the wires has already worn off in several places. These have been used with 5 month puppies. If it tears up with them it definitely won't last with a larger dog. Also not truly 50 ft long. They are over a foot short. Wouldn't matter much being a little over a foot off but I needed the 50 ft exactly.
