These battery cables are a great value! Some reviews criticized them for being so light but that is exactly what the description says..."light duty". For those applications these are certainly lighter and more flexible than the much heavier gauge would be and when you don't need the heavy ones why subject yourself to the hassle? They are well made and because the two wires are molded together you don't have the tangle problem that you have with separate cables. I actually bought them because I needed a 10 foot heavy 12volt cable to connect a power winch and these were much cheaper than buying bulk wire!
