At least for what I bought them for. I use them to route cables around the legs of a 4" telescopic tripod. The cables are fixed and the telescope is used in the dark (yes), so cable management is a safety priority. They are easy to use, handle cables well and keep them safe. I've been using them for about a year and they show no signs of wear or breakage. Literally no flaws. I bought two different lengths for convenience, and it's also easy to string them together to get extra long lengths (e.g. to run a cable along the scope itself).
