I provide sound for live music and speaking events. I purchased the cable protectors to cover cables running from our sound booth to the stage in areas where the cables would be stepped on and could cause someone to trip. I wasn't sure if they were the best ones for my needs and took a chance. They worked great! They are heavy and lay flat on grass and other surfaces. I've used them on 3 occasions right after purchasing them. I used them to cover a thick extension core and a couple of Cat 5 cords with no problems. They weren't to obtrusive and they were easily seen. I will be purchasing more in the future!
