According to my experience these purple cables are one of the best choices for industrial and scientific purposes. The pack consists of 3 durable 3ft+3ft cables to ensure easy charging of all my devices without any worry .These cables are highly durable and can withstand harsh industrial environments. The soft and tangle-free design makes them easy to use and transport. The only downside is that the length might not be suitable for larger premises. Overall, this pack is a great investment for any business in need of reliable cables..
